How to configure T1/E1 controller on Cisco 2800 router
1- check physical location of card slot to check run command
# sh diag
it will show you WIC slot no
WIC Slot 0:
VWIC2-1MFT-T1/E1 – 1-Port RJ-48 Multiflex Trunk – T1/E1
Hardware Revision : 0.0
2- initialize the E1 T1 controller card
PSTN(config)#card type ?
e1 E1
t1 T1
PSTN(config)#card type e1 ?
<0-2> Card slot number (always 0 for 1800 series & 2801 routers)
PSTN(config)#card type e1 ?
<0-2> Card slot number (always 0 for 1800 series & 2801 routers)
PSTN(config)#card type e1 0 ?
<0-3> WIC slot number (0:WIC, 1:Onboard for NM-HDV2)
PSTN(config)#card type e1 0 0 ?
<cr>
card type e1 0 0
It will create E1 or T1 controller as you defined card type.
controller E1 0/0/0
3- define the network clock network-clock-participate to use there own clock signals .
network-clock-participate
4- Define ISDN switch type its according to country and location .
primary-4ess Lucent 4ESS switch type for the U.S.
primary-5ess Lucent 5ESS switch type for the U.S.
primary-dms100 Northern Telecom DMS-100 switch type for the U.S.
primary-dpnss DPNSS switch type for Europe
primary-net5 NET5 switch type for UK, Europe, Asia and Australia
primary-ni National ISDN Switch type for the U.S.
primary-ntt NTT switch type for Japan
primary-qsig QSIG switch type
primary-ts014 TS014 switch type for Australia (obsolete)
isdn switch-type primary-net5 (I am configuring for ASIA)
5- Configure the framing and linecode
PSTN(config)#controller e1 0/0/0
PSTN(config-controller)#framing no-crc4 (confirm with telco )
PSTN(config-controller)#linecode hdb3 (confirm with telco )
6- Define ISDN channels Time slot
PSTN(config-controller)#pri-group timeslots 1-31 (For full PRI)
Now it will create data / voice channels and and signaling as serial interface
interface Serial0/0/0:15 (signaling channel )
to check all channels run command sh ip int brief
Now your ISDN Layer 1 and Layer 2 should be up.
to check ISDN status by the command
sh isdn status
Note :- one side of router either your side or ISP side router the E1 /T1 controller Serial interface should have command isdn protocol-emulate network otherwise ISDN layer 2 will not establish and it should be “MULTIPLE_FRAME_ESTABLISHED”
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
On T1 Card you must define framing and linecode under Controller T1
