Pri-group command

Hi;
I'm trying to configure my E1 controller on 2621XM router with having IOS (c2600-ipvoice-mz.123-7.T10.bin), but it's not showing in the controller configuration mode!!
please help how to enable it? and/or if there is some specific IOS release to support this command pri-group timeslots ...!
thanks

If you have a voice feature set the command should appear if you have the correct hardware.
Do you have a DSP card in your router?
Do a show diag and show voice dsp, maybe post the results if you're unsure...

How to fake ISDN b-channels as busy out of the pri-group timeslots definition ?

Hi, Cisco Support Community,
This is my first post here, so I hope I won't make mistakes... First, thanks for reading me.
I wanted to reuse an old 2811 to act as a SIP gateway on an ISDN primary rate interface. This router is featured with 2 PVDM2-8 modules, so that we're able to handle up to 16 simultaneous calls. So I ordered a pri with 10 channels, which is supposed to be more than enough for our usage.
Everything works fine, excepted that I discovered that the PRI which was delivered to us is a full one, meaning 30 B channels.
As a result, as incoming calls are dispatched round robin by the isdn line provider, when incoming calls start to be presented on b-channel 16, the call is rejected by the router with a "channel unavailable" message... The only way to have a successful incoming call is then to have 15 more unsuccessful tries so that the calls are presented on B-channel 1 again :-/
I have to wait for monday to deal with the line provider to sort this out, but meanwhile, I was trying to find a workaround.
My first try was to use B-channel negotiation on the serial interface (isdn negotiate-bchan resend-setup), but it seems that b channel negociation is disabled on the provider side.
So the other obvious solution would be to fake channels 17 to 31 as busy (isdn busy b_channel xx) ... But as the pri-group timeslots are 1-16, the related serial interface is serial0/0/0:15, and I'm unable to set busy B-channels over 15. And of course, I have no way to define pri-group timeslots 1-31 as I have not enough DSPs to handle more than 16.
I also tried to use the ds0 busyout directive within the E1 controller configuration, but while the command is accepted, it does not appear in the configuration
Below is my running configuration... If some of you can help, this would be much appreciated. Current IOS on the router is Version 12.3(11)T3
Kind regards,
Philippe Martorell

Trunk-group command under controller T1 in which IOS is available

Hi All,
Quick question, I would like to know if the trunk-group under the controller t1 is available in the 15.T train currently I have the following IOS
152-2T
153-1T
and neither IOS have the command. But in the 15.M train (151-4M) I have it.
Basically what I want to accomplish is to reserve 2 B channels for Emergency calls, something like this:
controller T1 0/0/0
pri-group timeslots 1-24
trunk-group Emergency timeslots 1
trunk-group Standard timeslots 2-24
Thanks in advance
Regards
Carlito

Hi,
The Chris is right, if you did not declare the trunk group before, he'll be available at the interface T1 Pri.
Ex:
trunk group Emergency
hunt-scheme longest-idle both
controller T1 0/0/0
pri-group timeslots 1-24
trunk-group Emergency timeslots 1
Regards.

AS5300 is reloading instantly on "pri-group timeslots 1-31" settings

Hello,
On AS5300 when any of the 4 E1 ports is connected and the "pri-group timeslots" are enabled the gateway instantly reloads, I can't see any error message. I have tried the following tests on my Cisco AS5300
1. software loopback on the ports - it does not restart (on     "pri-group timeslot" setting).
2. tried to disconnect one port from a functional gateway ( Cisco AS 5300, with same configuration)     and connect it to a port of new Cisco - it restarts (on "pri group     timeslot" setting)
3. with all cables disconnected and "pri-group timeslot" setting it     is working without restart, after the cable is plugged in, it     restarts
4. hardware         loopback on any of the ports and "pri-group timeslots" - it         restarts
5. Power off , plug out the module         boards (E1 and DSP boards), plug in the boards and power on -         doesn't help it keeps to restart on the "pri group timeslot"         setting
What could cause this issue?
Thank You,
Szabolcs Szasz

What is the IOS version of your AS5300?
In "show ver" information, what is the reboot cause? Is it a crash?
Probably the command "pri group timeslot" creates an unexpected condition that causes the crash.
In my experience an IOS upgrade solves this issues.

This behavior is only seen when the c1751 or c1760 voice gateway has a T1/E1 VWIC installed and the T1/E1 controller is in a DOWN state, either due to an actual outage or even due to administrative shutdown. The T1/E1 controller can be set up for a voice pri-group, voice ds0-group, data channel-group, or even nothing at all -- the key is that the controller is DOWN. Once the T1/E1 controller is brought back up the OUT STATus for all POTS dial-peer will return to an UP state and calls may terminate again on those POTS dial-peers.
Workaround:

Configure the command no dial-peer outbound status-check pots in global config mode.

Incorrect ouput of "groups" command

I setup iDS 5.1 server on Solaris 9 and client on Solaris8. I created one account (user1) and add it on 2 groups, but I could not get right output by running "groups" command, it only was displayed that this account just exist on one group (primary group). Please help, thanks in advance.
Here is the output on iDS client.
# cat /etc/nsswitch.conf
passwd: files ldap
group: files ldap
# su - user1
$ id
uid=10001(user1) gid=1699(GD699)

uniqueMember: uid=user1,ou=People, dc=cig,dc=mcel,dc=mot,dc=com
uniqueMember: uid=user2,ou=People, dc=cig,dc=mcel,dc=mot,dc=com
BTW, another thing strange really confused me, I also installed "ypldapd" (PADL/LDAP gateway )on Solaris 8 client, the output is right if I added "nis" on "group" line in /etc/nsswitch.conf.

At first I tried to set LC_ALL to ru_RU.UTF-8, but the result of sorting was still wrong.
The locale settings are in /usr/share/locale/, and /usr/share/locale/ruRU.UTF-8/LCCOLLATE is a symlink to a latin collation, which does not work for cyrllic characters, of course. You can consider this as bug, I guess.
/usr/share/locale/UTF-8/ does not have LC_COLLATE, so it is equivalent to LC_COLLATE=C, which means sorting strings by considering each string as an array of unsigned bytes, or sorting according to the Unicode code points. This usually gives the correct collation. export LC_ALL=C should have worked as well.
Setting LC_ALL (or LC_TIME) to ru_RU.UTF-8 has an effect that the date is output in Russian. for example:
$ export LCALL=ruRU.UTF-8
$ date
среда, 17 марта 2010 г. 02:45:07 (JST)
$ ls -ld /
drwxrwxr-t 31 root admin 1122 14 ноя 22:24 /
If you want to keep this behavior, then set only LC_COLLATE to C
$ export LCALL=ruRU.UTF-8
$ export LC_COLLATE=C
or create an alias like
alias sort='LC_COLLATE=C sort'

Group command

How would I find the groups for 4 users? I can type in the 'group' commandfor myself but want to build a script that will give me each persons name and all the groups they are in.
I am on a Solaris 7 os.

I'm not sure if I have your question right, but the "groups" command takes a list of users as the argument list. Example:
$ groups bin sys adm
bin : bin sys
sys : sys
adm : adm sys tty lp
That shows the group memberships of a number of default users.

Can not delete the ip igmp join-group command on NX2Ks.

Hi,
I have 1 NX5K & 1 NX2K (FEX) and configured PIM on them -Release 5.2(1)N1(1).
I configured on the NX2K's ports the ip igmp join-group command to statically bind a multicast group to an interface. The multicast PIM works fine but when I try to remove the ip igmp join-group command on any interface because not all should have this command, I cannot.
I have not found any bug on the 5.2(1)N1(1) version related to this behavior and the released notes not mentioned anything about this.
Any ideas...!?
-Sergio

Hello Sergio
FEX ports are meant to be L2 ports only and hence you should not be allowed to configure "ip igmp join-group" but looks like we do allow it which is a bug.. I will see if there is one filed for it and if not file a new one.
Thanks

Pri-group vs ds0-group

dear all
could anyone explain the difference bt these commands and when they should be used. thanks

Pri-group is used to configure a controller for an ISDN primary rate T1 or E1, often called a PRI. There is a common signalling channel called a data (D) channel, and bearer channels (23 for T1, 30 for E1) that carry the calls.
Ds0-group is used to configure a channelized T1. Cisco refers to this as CAS or channel associated signalling. The supervision is done on each individual channel using a technique called robbed bit signalling. Digits are sent using DTMF tones on each channel.
PRIs are generally preferable in that the call setup time is much faster, and caller ID is easily implemented. CAS is sometimes the only choice in small towns, and can usually be ordered with only the number of channels needed, while many Telcos will only sell a full or half PRI.

Channel-group command

Could someone point me to a link about information about this command besides its options and such. If you dont know of a link but know the command, some of the questions I'm having include:
(1) what are the benefits of this command and why would you use this configuration?
(2) What platforms will this work for?
(3) If using between two switches and lets say you have four fiber links between the two, can you put three of the links into a channel-group and leave the other link out of the channel-group?
(4) Do the interfaces in the channel-group have to be in the same slot (same switching module) to be in a channel-group?
(5) Again, if you have two switches connected by four fiber links and you put each side of interfaces in a channel-group, do both sides have to be the same channel-group number?
(6) Neglecting that it is a hardware or line problem, what might be the reason for some of the interfaces in a channel-group to come up while others dont assuming that all the interfaces are configured exactly the same?

(1) what are the benefits of this command and why would you use this configuration?
>> channel-group x mode is an interface configuration to group identical interfaces in a combined logical interface, think of it as small pipes being combined to create a bigger pipe so that you can have more flows.
(2) What platforms will this work for?
>> channel-group is specific to catalyst running IOS like 2950, 2955, 2960, 2970, 3550, 3560, 3750, cat4000 with sup II+ or above, cat6000 with sups running Native IOS. For catalyst running it will be "port channel" command.
(3) If using between two switches and lets say you have four fiber links between the two, can you put three of the links into a channel-group and leave the other link out of the channel-group?
>> yes, by virtue of channel it will have a lower cost than the single interface therefore STP will block the single interface because it has a higher path cost to the root (STP can be discuss in a separate discussion).
(4) Do the interfaces in the channel-group have to be in the same slot (same switching module) to be in a channel-group?
>> No it does not have to be but they have to be identical. You cannot channel two ports where one is 100 MB and the other is a gig port.
(5) Again, if you have two switches connected by four fiber links and you put each side of interfaces in a channel-group, do both sides have to be the same channel-group number?
>> NO, channel group have local significance. If on switch A port 1 and 2 are in channel-group 1 and port 1 and 2 are connecting to port 3 and 4 of switch B. In switch B port 3 and 4 can be in channel-group 2 or 3 or 1 if you want to keep them the same for administrative sanity.
(6) Neglecting that it is a hardware or line problem, what might be the reason for some of the interfaces in a channel-group to come up while others dont assuming that all the interfaces are configured exactly the same?
>> cabling not right, interfaces in the same channel group are not alike, problem with the other end, or bug but this seldom is the case.

NTP access-group command

Gday All,
If I apply the configuration to my router
ntp access-group peer NTP_ACL
Will this mean that my router can still be quieried, from any source, for NTP and can only query the servers allowed in NTP_ACL?
If I apply the configuration to my router
ntp access-group serve NTP_ACL
Will this mean that my router can query any router for NTP updates and only restricted hosts can query my router for NTP updates?
Any feedback is greatly appreciated.

Thomas
You would think that this is the way that it would work. But my experience is that if you apply one of the ntp access group functions that it will apply both types of filtering - and the function that does not have any permits will not allow that access. So my advice is that if you will apply one ntp access group that you should apply both.

CME - can not dail PSTN (out going calls )

hello ,
i have CME installed on 2900 router , incomming calls are working fine but i can dial PSTN calls.
below error is comming in Debug:
Outgoing call from gateway: gives diconnect cause value = 34 no circuit

Hi Aslam,
1.Could you please explain the complete network topology and please upload the debugs that you collected with the called and the calling number.Also attach the relevant controller config, serial interface config, dial-peer etc to analyze.
2.Cause value 34 implies that there is a mismatch in channel mapping either on your end or the provider's end.
3.So we need to check if we are sending this error message or if we are receiving this error message.
If we are receiving this error message, then provider needs to correct the channel mapping on their end.
4.If we are using H323 then try to change the isdn channel order using this command on gateway
"isdn bchan-number-order" as well as try changing the channel order from under the gateway on CUCM, if we have a CUCM in the network topology.
5.Make sure we have configured only those channels that we are allowed to inside a Controller for pri group command.
Thanks & Regards,
Mudit Mathur

Channel assignment

Hi,
Can you help me to resolve this issue?
1.I have sites A (Singapore) and B (India)
2.At site A (Singapore) there is a Cisco router with VWIC-2MFT-T1 is connected to PBX T1 port.(120 users are sitting with a hand set)
3.This router is also connected to IPLC by means of T1.
4.At site B (India) there is a Cisco router 1841 with VWIC-2MFT-E1 and is connected to PBX E1 port.
5.This site B router is connected to the IPLC cloud by means of LL 2Mbps.
6.My problem is whenever the dialer at Site A (Singapore) use the 16th channel and generate the voice call to India over the IPLC cloud, Can the India router recognize the voice call in the same 16 channel? If so how to do it? Should I have to use the CoS to achieve this?
Best Regards,
S.Venkataraman

T1 and E1 Controllers
Cisco controllers negotiate the following parameters between an access server and a central office: line coding, framing, clocking, DS0/time slot provisioning, and signalling.
Time slots are provisioned to meet the needs of particular network scenarios. T1 controllers have
24 time slots, and E1 controllers have 30 time slots. To support traffic flow for one ISDN PRI line in a T1 configuration, use the pri-group command. To support traffic flow for analog calls over a channelized E1 line with recEive and transMit (E&M -- also ear and mouth) signalling, use the cas-group 1 timeslots 1-30 type e&m-fgb command. Most telephone companies do not support provisioning one trunk for different combinations of time slot services, though this provisioning is supported on Cisco controllers. On a T1 controller for example, time slots 1 to 10 could run PRI, time slots 11 to 20 could run channel-associated signalling (CAS), and time slots 21 to 24 could support leased-line grouping.
The following example configures one of four T1 controllers on a Cisco AS5300 access server:
as5300# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
as5300(config)# controller t1 ?
<0-3> Controller unit number
as5300(config)# controller t1 0
as5300(config-controller)# framing esf
as5300(config-controller)# linecode b8zs
as5300(config-controller)# clock source line primary
as5300(config-controller)# pri-group timeslots 1-24
as5300(config-controller)#
This example supports modem calls and circuit-switched digital calls over ISDN PRI.
Non-ISDN Channelized T1 and Channelized E1 Lines
A channelized T1 or channelized E1 line is an analog line that was originally intended to support analog voice calls, but has evolved to support analog data calls. ISDN is not sent across channelized T1 or E1 lines. Channelized T1 and channelized E1 lines are often referred to as CT1 and CE1. These channelized lines are found in "old world," non-ISDN telephone networks.
The difference between traditional channelized lines (analog) and nonchannelized lines (ISDN) is that channelized lines have no built-in D channel. That is, all 24 channels on a T1 line only carry data. The signalling is in-band or associated to the data channels. Traditional channelized lines do not support digitized data calls (for example, BRI with 2B + D). Channelized lines support a variety of in-band signal types, such as ground start, loop start, wink start, immediate start, E&M, and R2.
Signalling for channelized lines is configured with the cas-group controller configuration command. The following example configures E&M group B signalling on a T1 controller:
as5300# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
as5300(config)# controller t1 0
as5300(config-controller)# cas-group 1 timeslots 1-24 type ?
e&m-fgb E & M Type II FGB
e&m-fgd E & M Type II FGD
e&m-immediate-start E & M Immediate Start
fxs-ground-start FXS Ground Start
fxs-loop-start FXS Loop Start
r1-modified R1 Modified
sas-ground-start SAS Ground Start
sas-loop-start SAS Loop Start
as5300(config-controller)# cas-group 1 timeslots 1-24 type e&m-fgb
as5300(config-controller)# framing esf
as5300(config-controller)# clock source line primary
as5300(config-controller)#
