trunk-group

Last Updated : Nov 06, 2012 |
Used within the sls context to enter a second-level subcontext for administering trunks for SLS. After issuing this command, the prompt changes to sls-trunk-group-<tgnum>. Type exit to leave the trunk-group context, and return to the sls context.

Parameters

Parameter
Description
Possible Values
Default Value
tgnum
The required trunk group number
1-2000
group-type
The trunk group type. This argument is required to enter the trunk-group context.
loop-start (analog)
did (analog)
ground-start (analog)
bri (ISDN basic rate)
t1isdn (ISDN primary rate on 1.544 Mbps facility)
e1isdn (ISDN primary rate on 2.048 Mbps facility)
t1inband (non-ISDN rate on 1.544 Mbps facility)
e1inband (non-ISDN rate on 2.048 Mbps facility)
You can create a trunk group that does not have any assigned members. Once a valid port is assigned as a trunk group member, this trunk group becomes active and may be employed by SLS call processing for incoming/outgoing trunk operation. The slot-configuration table will be used together with the port capacity for the given module to determine the validity of a port assignment at administration time.
As a corollary to this, there may not be more active trunk groups than there are physical trunk members within a given gateway. Secondly, a combo-port may only be used for one active assignment. For example, the analog station/DID trunk ports may be either allocated to serve as an analog station or as an analog DID trunk, but not BOTH.

Example

To enter the second-level subcontext of sls-trunk-group-<tgnum> where the trunk group is number 200 of type loop-start:

Gxxx-001(sls-trunk-group-<200>)#
