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
