VWIC-2MFT-E1 vs 2xVWIC-MFT-E1. Troubles. Please help

[SludnevTN_2]

I wanted to save one slot in my 2621XM - this is one of main reasons I have bought VWIC-2MFT-E1 instead of 2 one-head controllers. Also I installed 1 AIM-VOICE30. (I need 2 e1 PRIs with only 16 timeslots in each)

I have 2 E1 links, first - from my telephony service provider and second link from my PBX (AVAYA). So i see my future scheme this way:

controller e1 0/0

description - To Service Provider.

pri-group timeslots 1-16

!

controller e1 0/1

description - To PBX

pri-group timeslots 1-16

I want a call arrived from SP will be sent to PBX and a call arrived from PBX well be sent to SP.

But I can not configure times slots on second e1, just see the output...

GK(config)#controller e1 0/0

GK(config-controller)#pri-group timeslots 1-16

GK(config-controller)#

Can somebody help?

Please confirm my correct understanding of the commands:

network-clock-participate wic 0 - this tells IOS that Controller in slot "HWIC0" will be watching for synchronization

network-clock-select 1 E1 0/0/0 - this points IOS to watch for synchronization in the exact "head" - 0.

!

controller E1 0/0/0 ! This head will TAKE synchronization from SP

framing NO-CRC4

pri-group timeslots 1-16

description SP PRI

clock source line ! hidden

!

controller E1 0/0/1 ! This head will GIVE synchronization PBX

framing NO-CRC4

pri-group timeslots 1-16

description PBX PRI

clock source internal

!

interface Serial0/0/0:15 - SP Serial

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

no cdp enable

!

interface Serial0/0/1:15 - PBX Serial

isdn protocol-emulate network !!! Is this necessary?

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

no cdp enable

Am I correct?

Yes, I told you the principles before, it's not always necessary to go over configuration.

Yes, I told you the principles before, it's not always necessary to go over configuration. - I am sorry, I really do not understand what this means... Does it means that the principle is - Answer the questions and never give a config?

[SludnevTN_2]

Thank you anyway. Your answers were really helpful and very quick.
