How to configure Cisco Router T1 for MGCP

How to configure Cisco Router T1  for MGCP

Below steps checked on  Cisco 2811 and 2911 Routers

1- Check the  VVIC  location

R1#sh inventory
NAME: “2811 chassis”, DESCR: “2811 chassis”
PID: CISCO2811 , VID: V05 , 

NAME: “VWIC2-1MFT-T1/E1 – 1-Port RJ-48 Multiflex Trunk – T1/E1 on Slot 0 SubSlot 0“, DESCR: “VWIC2-1MFT-T1/E1 – 1-Port RJ-48 Multiflex Trunk – T1/E1”

 

Show inventory command shows you the location installed VVIC card in our case it is installed on Cisco Router Slot 0.

2- Now Define card type  as you want to use E1 or T1

card type t1 0 0

Now it will create  a controller port  as Controller T1 0/0/0

3- Now configuring clocking

network-clock-participate wic 0
network-clock-select 1 T1 0/0/0

4- Now configure ISDN switch type

isdn switch-type primary-ni

5-  Now configure Controller T1 0/0/0

framing esf
linecode b8zs
clock source line
pri-group timeslots 1-24 service mgcp

 

you will not see above command in show run you will see only below config

controller T1 0/0/0
cablelength long 0db
pri-group timeslots 1-24 service mgcp  

6-  Now configure Serial interface  :23   show T1 :15 show E1

interface Serial0/0/0:23

isdn outgoing display-ie
isdn outgoing ie redirecting-number
isdn negotiate-bchan
isdn bind-l3 ccm-manager

 

Now you configuration is done for MGCP configuration .

Note you will not see ISDN status up

******* Network side configuration *******
dsl 1, interface ISDN Switchtype = primary-ni
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = TEI_ASSIGNED

 

To check ISDN status without configuration MGCP use below command

no isdn bind-l3 ccm-manager

Now check show isdn status  you must be able to see

 

******* Network side configuration *******
dsl 1, interface ISDN Switchtype = primary-ni
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED

 

 

All command

card type t1 0 0

network-clock-participate wic 0
network-clock-select 1 T1 0/0/0

isdn switch-type primary-ni

 

controller T1 0/0/0
framing esf
linecode b8zs
clock source line
pri-group timeslots 1-24 service mgcp

 

int serial 0/0/0:23
isdn outgoing display-ie
isdn outgoing ie redirecting-number
isdn negotiate-bchan
no isdn bind-l3 ccm-manager
