Fractional inbound PRI routing

[Chris Deren]

I have a scenario for a customer in Europe where they have 2 E1-PRIs, each PRI is configured to allow the first 10 channels to be only for inbound and remaining 20 channels to be inbound/outbound.  If I send a call out on channel that is only allowed for inbound I get the following and another port is not tried:

        Cause i = 0x82D21803A98381 - Identified channel does not exist

Since both PRIs are configured this way I cannot play with b-channel ordering. I found this thread, but it does not seem you can add the trunk-group command under controller:

Has anyone done similar configuration and found a way to make it work?

What HW/SW are you running? You should be able to create trunk-group under controller.

3925 with NM-HDV2-2T1/E1, but I also looked at another 39XX with VWIC2-2MFT-T1/E1 in HWIC slot and dont see the option.  IOS is 15.1.4M4.

Controller configuration commands:

  cas-custom        cas group customization configuration

  channel-group     Specify the timeslots to channel-group mapping for an interface

  clock             Specify the clock source for a DS1 link

  default           Set a command to its defaults

  description       Controller specific description

  detect            Enable detection of loopback request

  ds0               ds0 commands

  ds0-group         Configure group of timeslots to a particular signaling type

  exit              Exit from controller configuration mode

  framing           Specify the type of Framing on a E1 link

  guard-timer       Guard timer (0-20) for xcsp calls - timer duration and accept/reject on expiry

  help              Description of the interactive help system

  line-termination  Specify the line termination for E1

  linecode          Specify the line encoding method for a E1 link

  loopback          Put the entire E1 line into loopback

  mode              Configure the controller mode

  no                Negate a command or set its defaults

  pri-group         Configure the specified timeslots for PRI

  shutdown          Shut down a E1 link (send Blue Alarm)

  snmp              Modify SNMP controller parameters

  tdm-group         Configure DS0 group for TDM

Configure pri-group first, then trunk-group command will appear.

Paolo,

It was not there becuase I had trunk group assigned to the D-channel interface, as soon as I removed it from serial interface it now appeared.  Thanks.

Yeah, one or the other.

Thanks for the nice rating and good luck!

Chris,

Was late to see this, I had love to give something back to you especially for how great you have been on the forum! I am happy though that Paolo helped out..I thought I should put in a few line of configs here just in case someone looks into this thread in the future...
