Interface Configuration
7210 SAS M, T, X, R6, R12, Mxp, S, Sx Interface Configuration Guide Page 217
signal-mode
Syntax no signal-mode {cas}
Context config>port>tdm>ds1
config>port>tdm>e1
Description Platforms Supported: 7210 SAS-M.
This command activates the signal mode on the channel.
When enabled, control signals (such as those for synchronizing and bounding frames) are carried in the
same channels as voice and data signals. Configure the signal mode before configuring the Cpipe service to
support T1 or E1 with CAS.
Refer to the 7210 SAS Services Guide, “Creating a Cpipe Service”, for information on configuring a Cpipe
service.
This command is valid when:
• T1 framing is set to esf or sf
• E1 framing is set to g704 or no-crc-g704.
Note: On the 7210 SAS, CAS is enabled at the port level, rather than at the 64 kb/s channel level. This
means that control signals and voice and data signals are all carried in the same channels. However, T1 and
E1 links with a mix of voice and data channels cannot be transported directly across a 7210 SAS network.
For a workaround, please contact Alcatel-Lucent technical service representatives.
This limitation does not apply to Serial Data Interface card and E&M card traffic transported over MPLS as
the signaling is transported in individual pseudowires.
Parameters cas — Specifies channel associated signaling.
timeslots
Syntax timeslots timeslots
no timeslots
Context config>port>tdm>ds1>channel-group
config>port>tdm>e1>channel-group
Description Platforms Supported: 7210 SAS-M.
This command defines the list of DS-0 timeslots to be used in the DS-1 or E-1 channel-group. The timeslots
need not be consecutive.
The no form of this command removes DS-0 timeslots from a channel group.
Default no timeslots — Non-ATM channel groups.
Parameters timeslots — Specifies the timeslot(s) to be associated with the channel group. The value can consist of a list
of timeslots. Each member of the list can either be a single timeslot or a range of timeslots.
Values 1 — 24 for DS-1 interfaces
2 — 32 for E-1 interfaces
