How to configure T1/E1 controller on Cisco 2800 router

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
