reassembly (SAR) port. The internal interface number is one greater than the highest
DSL interface number on the module. For example, the following command output
indicates a 48-port LIM in slot 1, a 72-port LIM in slots 2 and 4, and a 24-port LIM in
slot 6:
admin> dir atm-internal
42 05/09/2003 08:41:34 { shelf-1 slot-1 49 } 1:1:49
42 05/09/2003 08:41:34 { shelf-1 slot-2 73 } 1:2:73
42 05/09/2003 09:30:38 { shelf-1 slot-4 73 } 1:4:73
42 05/09/2003 08:41:34 { shelf-1 slot-6 25 } 1:6:25
38 05/09/2003 08:41:30 { shelf-1 first-control-module 1 } 1:8:1
For a DSL interface to handle PPPoA and PPPoE incoming calls, you must configure
an ATM circuit between the external DSL interface and the LIM’s internal ATM
interface. The ATM circuit configuration must specify the nailed group of the internal
interface as the second leg of the circuit (in the
atm-connect-options
subprofile).
Note
The system prevents configuration of a circuit from one LIM to the ATM
internal interface of another LIM, or configurations that attempt to use the internal
interface of a LIM in other ways.
To determine the nailed group of a LIM’s internal ATM interface, use the
which
command. Following is a sample command for the internal interface of a 72-port LIM
in slot 4:
admin> which -n { 1 4 73 }
Nailed group corresponding to port { shelf-1 slot-4 73 } is 2271
The following commands enable an SDSL interface in slot 4 and configure an ATM
circuit from the DSL interface to the LIM’s ATM internal interface:
admin> read sdsl { 1 4 1 }
admin> set enabled = yes
admin> write -f
admin> new connection cir-1
admin> set active = yes
admin> set encapsulation-protocol = atm-circuit
admin> set atm-options vci = 38
admin> set atm-options nailed-group = 151
admin> set atm-options atm1483type = aal5-vc
admin> set atm-connect-options vci = 36
admin> set atm-connect-options nailed-group = 2271
admin> write -f
