Re: Configuring E1 Controller

To configure an E1 controller as a normal PRI line, use the following configurations :

controller E1 6/0

framing NO-CRC4

pri-group timeslots 1-31

D channel config:

interface Serial6/0:15

description

ip unnumbered FastEthernet0/0

encapsulation ppp

dialer rotary-group 1

dialer-group 1

isdn switch-type primary-net5

no cdp enable

Any ISDN calls can land in this slot in this case.

To configure an E1 controller for sync serial interfaces, use:

controller E1 6/1

framing NO-CRC4

channel-group 0 timeslots 1

channel-group 1 timeslots 2

channel-group 2 timeslots 3

.

.

channel-group 30 timeslots 31

interface Serial6/1:0

description

ip address x.x.x.x y.y.y.y

encapsulation ppp

no ip route-cache cef

ip mroute-cache

Cheers

Also please check for the isdn switch type and framing in your region.

Hi sachinraja

Are the timeslot 0 and 15 usable for channel groups or no? How many channel-groups could be define?

Thanks alot.

Re: Configuring E1 Controller

In framed E1 mode you have timeslots 1-31 available, so you can have 31 channel-groups with 1 timeslot each. Timeslot 0 is used for framing so it is not available. Timeslot 15 is a normal timeslot like any other.

In E1 ISDN PRI mode, timeslot 16 is used for signalling (the D channel, Serial x:15) and timeslots 1-15 and 17-31 are your 30 B channels.

Thanks again after along time.

Hi walu,

this is the config for unframed g.703:

controller E1 0/0

channel-group 0 unframed

!

interface Serial0/0:0

ip address ...

...

Just configure the serial like any other serial interface.

regards

Re: Configuring E1 Controller

Hi ,

we are using an Cisco 3640 Router with an 2 Port Pri Network Module and it seems that this command is not supported with this card.

If there are no other possibilities i think that we should use an new card (VWIC-1MFT-G703). Did someone knew if this card supports this command?
