Configuring E1 Controller

[walu]

Hello together,

i like on configure an E1 Controller for an unchannelized line. This line has an g.703 standard, its like an clear channel.

Does somebody have an similar constellation and can provide an example configuration ??

Thanks in advance for all responses

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.

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.

Now, I look For a Cisco Document for

configuration an E1 controller for sync serial interfaces.

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.

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?
