3-16 Setting the Operational Parameters RADview-SC/TDMoIP IPmux-11
Parameter Possible Values / Remarks
Line Type Line type affects the number of bits per second that the link can reasonably carry. It also
affects the interpretation of the port performance statistics.
For E1 ports:
Framed (G.704), Framed-CRC, Framed-MF, Framed-CRC-MF
Unframed (G.703) - Use when the data being transmitted is unframed.
For T1 ports:
ESF - Extended SuperFrame
D4 - AT&T D4 format
Unframed - Use when the data being transmitted is unframed.
Note: Line Type is grayed out and can't be changed when a bundle is defined over the
selected interface.
Line Code
(only applicable
for T1 ports)
Type of Zero Code Suppression used on the link
B7ZS, B8ZS, AMI
Idle Code
(not applicable
when the Line
Type is unframed)
Byte pattern of the data transmitted in the E1/T1 Framer idle timeslots
0 to FF
Signaling Mode
(only applicable
for T1 ports)
Type of signaling used on the link
None, Robbed Bit
Line Interface T1 device operation mode
DSU, CSU
Note: Only applicable for T1 ports
Line Length (feet)
0-133, 134-266, 267-339, 400-533, 534-655
Note: Only applicable for T1 ports with Line Mode DSU
Line Buildout (dB) Transmit line gain for T1 CSU line mode
0, -.5, -5, -2.5
Note: Only applicable for T1 ports with CSU Line Mode
Restore Time
(sec)
Used to change the sync. Algorithms to reduce the time required for the port to return to
normal operation after a RED (LOF - loss of frame synchronization) alarm.
1, 10
Note: Only applicable for T1 ports. Not applicable when the Line Type is Unframed.
OOS Signaling Defines the value to be sent as a signal after alarm detection
Space - Both A and B signaling bits are forced to '0' during out-of-service periods
Mark - Both A and B signaling bits are forced to '1' during out-of-service periods
Space_Mark - A and B bits are forced to '0' for 2.5 seconds; then they are switched to '1'
until out-of-service condition disappears
Mark_Space - A and B bits are forced to '1' for 2.5 seconds; then they are switched to '0'
until out-of-service condition disappears
Space Signaling
Code
Space Signaling Code – value to be sent as a signal during the first 2.5 seconds after
alarm detection
E1, T1-ESF: 1..F
T1-SF(D4): 1..4
