Selects the framing for the network side of the DSU/CSU.
Values
ESF, D4
Default: ESF
Sets the network side line coding.
Values: AMI, B8ZS
Default: B8ZS
Sets the timing source to synchronize the unit's internal timing generators. In
all cases, slips are controlled to occur on frame boundaries at the Network
ports when timing synchronization is lost. The options are as follows:
Network − Internal, Network
Definitions of the timing sources are as follows:
Internal – The unit's internal frequency standard (T1 1.544 Mbps ± 50 bps)
is used for all timing.
Network – Timing is derived from the Network port recovered clock.
Determines whether ones density insertion is activated after 15 zeros. This
parameter is ignored if the Coding parameter is set to "B8ZS."
Values: Disable, Enable
Default: Disable
Lets you establish which performance messaging standard will be employed
to initiate Performance Report Message (PRM) functions. Setting this field to
"Enable" instructs the unit to use ANSI T1.403, which sends a PRM once
every second. Setting this field to "Disable" instructs the unit to use AT&T
TR54016, which provides performance reporting on request only.
Values: Disable, Enable
Default: Disable
Determines if the unit will attempt to discover active DS0s (after power-up,
Save and Restart). Active DS0s will then be assigned to the first associated
network service.
Values: Disable, Enable
Default: Disable
Specifies the rate at which each discovered DS0 will be set.
Values: As 56K/64K
Default: As 64K
NOTICE:
The unit will search for active DS0s for a maximum of 7 seconds if
learning "As 64k" and for 30 seconds if learning "As 56K."
