Configuring E1

Unanswered Question
Sep 15th, 2008

Have Vwic-wmft-e1. Controller shows down/down with increasing line code violations. Have verified framing /coding/isdn switch type with vendor. Card has AL and CD lights on (yellow and green). shut /no shut does nothing. Site is in India, if that helps. Using no-crc4/hdb3. CM is 6.11

I have this problem too.

Hi,

This is what we have set-up for a E1 in the UK -

sh contr e1

E1 0/0/0 is up.

Applique type is Channelized E1 - balanced

Framing is CRC4, Line Code is HDB3, Clock Source is Line.

From the running-config

!

card type e1 0 0

!

isdn switch-type primary-net5

isdn voice-call-failure 0

!

voice-card 0

no dspfarm

!

controller E1 0/0/0

pri-group timeslots 1-31

!

interface Serial0/0/0:15

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

no cdp enable

!

Your ISDN switch-type will probably be different. If you have a sh run. show isdn stat, sh contr e1 - that would be handy.

Thanks for your response. Here are the requested files. What troubles me is that when I use a crossover, I get the CD light. Replaces it with a Cat5, CD light goes off, but either way, no status changes on controller

E1 0/0/0 is down.

Applique type is Channelized E1 - balanced

Receiver has loss of frame.

Hi,

There may be a few commands that may need to be tweaked, nut l would contact your Telco as Layer 1 is showing as de-activated.

Global ISDN Switchtype = primary-net5

ISDN Serial0/0/0:15 interface

dsl 0, interface ISDN Switchtype = primary-net5

Layer 1 Status:

ACTIVE

If your E1 controller is in ?down/down" state, most likely you have a physical problem with the link. Confirm with your provider that they have all the same parameters as you configure in term of Framing and Linecode. In the lab, when you have wrong Framing/Linecoding, the controller will be down, but the moment I configure correct parameters, controller comes to up/up state even without "isdn switching" and PRI-DS0 configured.

In CUCM, if my provider has the following:

ISDN Switch Type - ETSI

.Line Coding - hdb3

.Framing - crc-4

I do not have these options on the MGCP for the gateway in CUCM. Only B8z3 or AMI.

How does this work in Taiwan then? I cant get my physical layer up

The {ISDN Switch Type - ETSI

.Line Coding - hdb3

.Framing - crc-4 ) is an E1 configuration.

Hi tcatlinins,

You may have a card type command set to T1.

Thats why you only see he B8zs which is a T1 config.

You may need to set the card type command

card type e1 slotno.
