• Select 2 for M13 framing.
9. From the Network Provisioning menu, select DS3 TIMING and press ENTER.
10. Input a value to set the desired DS3 timing and press
ENTER.
• Select 1 for Loop timing if the M13 MUX connects to a network that provides timing.
• Select 2 for Local timing if the M13 MUX provides the master timing source for the
circuit.

• Select 1, DISABLE, to ignore all out-of-band requests (FEAC and DS2 C-BIT). The M13
MUX still responds to individual T1 in-band CSU/NIU loopbacks if configured with the
T1/E1 Loopback Detection menu.
• Select 2, FEAC/C-BIT, to allow the M13 MUX to respond to remote loopback requests
received over either the DS3 Far End Alarm and Control (FEAC) channel and/or DS2-
level C-bits. This mode is valid for both C-BIT and M13 framing formats.
