3Com T1/PRI Forcing receiver reframe on the span lines, Forcing the NAC to master the TDM bus

Dual T1/PRI Commands 3-3

Menu Options	Forcing receiver reframe on the span lines
4 and 6	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	Disconnecting calls on specific span line B-channels
5 and 7	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 channels)
	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	Entering and exiting locally initiated loopbacks on the span lines
9 and 10	Issue loopback tests to verify that the span’s framer circuitry is functioning
	properly and to test Telco links. Menu options 9 and 10 control loopback
	tests for span lines 1 and 2. Initiate or terminate loopback tests from
	these prompts.
	This command turns the local interface into a “mirror” facing back
	toward the network.
