Configuring T1 or E1 module connections
To set up UNI or IMA ports for a T1 or E1 module, apply the following procedure
after installing the module and connecting it to the physical T1 or E1 line. The UNI
and IMA configuration procedures are somewhat different, as shown in the examples
that follow the general procedure.
Step
1
Configure the ds1-atm
profile for the physical
link.
2
Create and configure
an imagroup profile.
9-28
Setting
Not currently used. Indicates the cross-connect index in the
AToM MIB. For related information, see the Stinger Private
Network-to-Network Interface (PNNI) Supplement.
This is a read-only field.
Subprofile containing options for configuring an ATM
terminating connection or the first (incoming) leg of an
ATM circuit.
Subprofile containing options for configuring the second
leg of an ATM circuit.
Traffic contract name(s) for the upstream and downstream
traffic on the ATM circuit.
AAL configuration options that are set by the system.
Specifies whether a soft permanent virtual circuit (SPVC)
connection is for a user or for a signaling channel.
The field is read-only and has one of two values:
default—Represents any normal user connection.
cpcs—Common part convergence sublayer. Indicates
that the profile was created automatically for use by the
ATM signaling control channel.
Explanation
A nailed group must be assigned to each ds1-atm profile.
Physical lines that are part of the same IMA group must
have the same nailed group number assigned in their
respective ds1-atm profiles.
Physical lines that are used to support UNI ports must
each have a unique nailed group number.
When you are using the IMA mode, ds1-atm profiles are
bound to the imagroup profile by the nailed group
number. The same nailed group number used in the
ds1-atm profiles must also be assigned to the ima-group
profile.
This step is unnecessary for DS1 lines that support UNI
ports.
