Interface Configuration Guide 7705 SAR Interfaces
Edition: 01 3HE 11011 AAAC TQZZA 473
• T1/E1 ports on the 7705 SAR-M
• T1/E1 ports on the 7705 SAR-X
• T1/E1 ports on the 7705 SAR-A
• T1/E1 ports on the 4-port T1/E1 and RS-232 Combination module
Default line signal failure alarms are not issued
signal-mode
Syntax [no] signal-mode cas
Context config>port>tdm>ds1
config>port>tdm>e1
config>port>tdm>ds1>channel-group
config>port>tdm>e1>channel-group
Description This command enables or disables Channel Associated Signaling (CAS) at the port and
circuit levels. When enabled, control signals (such as those for synchronizing and bounding
frames) are carried in the same channels as voice and data signals.
If the signal mode for a DS1 or an E1 port is configured for no signal-mode, then all
DS0/64 kb/s channels within the DS1 or E1 port will not be enabled for CAS. Individual
channel groups within that DS1 or E1 port inherit this state and cannot be changed.
If the signal mode for a DS1 or an E1 port is configured for signal-mode cas, then any new
channel groups default to signal-mode cas and any existing channel groups can be
individually changed from cas to no signal-mode.
The signal mode must be configured for CAS before creating a Cpipe service that supports
T1 or E1 with CAS. Refer to the 7705 SAR Services Guide, “Creating a Cpipe Service”, for
information on configuring a Cpipe service.
This command is valid only on the 16-port T1/E1 ASAP Adapter card, 32-port T1/E1 ASAP
Adapter card, 2-port OC3/STM1 Channelized Adapter card, 4-port DS3/E3 Adapter card, or
4-port T1/E1 and RS-232 Combination module when DS1 framing is set to esf or sf, or E1
framing is set to g704 or no-crc-g704.
Parameters cas — specifies channel associated signaling
ssm
Syntax ssm
Context config>port>tdm>e1
Description This command accesses the context to configure E1 Synchronization Status Messaging
(SSM) parameters.
