DS3 Framing

Set the framing format to match the format of the receive signal at

the network interface.

C-BIT PARITY and M13 framing formats are

supported. Select

AUTO to allow the interface to detect the framing

type automatically.

Line Length

Set the line length to reflect the physical length of the DS3 network

line. Set to

LONG if the cabling distance exceeds 225 feet; set to

SHORT if the distance is less than 225 feet.

DS3 Timing

Set the timing to LOOP if the T3SU 300 is to derive timing from the

network; set to

LOCAL if the unit is to be the master timing source

for the circuit. In most cases, the unit should be configured for

LOOP timing.
