Dual T1/PRI Commands 3-3
Menu Options
4 and 6 Forcing receiver reframe on the span lines
Issuing command options 4 or 6 forces the T1 framer to reframe or
re-synchronize incoming data on span line 1 or 2.
Use these options if error conditions occur. Observe error conditions
through span line 1 and 2 Alarm/Event status screens.
Menu Options
5 and 7 Disconnecting c alls on specific span line B-channels
Options 5 and 7 allow you to disconnect calls on specific B-channels,
or time slots, on span lines 1 and 2. Enter the number of the channel or
channels you wish to disconnect calls on at the command prompt.
Valid channels are 1–23. Channel 24 is reserved as a D-channel.
Attempting to disconnect a call on channel 24 will produce an ERROR
message and reject the entire command even if other valid channels were
entered.
Use the following syntax when configuring this option:
BC# (for a single channel)
BC#,BC#,BC#,... (for single, non-sequential c hannels)
BC#-BC# (for a range of channels)
Where:
BC# = B-Channel number (1–23)
Menu Option 8 Forcing the NAC to master the TDM bus
This feature is not supported.
Menu Options
9 and 10 Ente ring and exiting locally initiated loopbacks on the span lines
Issue loopback tests to verify that the span’ s fr amer cir cuitr y is functi oning
properly and to test Telco links. Menu options 9 and 10 control loopback
tests for span lines 1 and 2. Initiate or terminate loopb ack tests from
these prompts.
This command turns the local interface into a “mirror” facing back
toward the network.
