SendCode The type of code being sent across the DS1 interface by the device. Values
are 1 - 8 and have the following names:
1=dsx1SendNoCode
2=dsx1SendLineCode (T1 lines only)
3=dsx1SendPayloadCode (reserved for future use)
4=dsx1SendResetCode (T1 lines only)
5=dsx1SendQRS (T1 lines only)
6=dsx1Send511Pattern (T1 or E1)
7=dsx1Send3in24Pattern (T1 or E1)
8=dsx1Send1in16 (T1 lines only)
LoopConfig The loopback configuration of the DS1 interface. Values are 1 - 4 and have
the following names:
1=dsx1NoLoop
2=dsx1PayloadLoop
3=dsx1LineLoop
4=dsx1OtherLoop, means local loopback on this device
LineSignalMode Signal mode for transmit direction. In the receive direction, the mode is
always set to robbed bit (2). Values are 1 - 4 and have the following names
and meanings:
1=none, means reserve no bits and set channel bandwidth to 64 kbps.
2=robbedBit, applies to T1 Channel Associated Signaling. Use a 56 kpps
channel for this mode. You can select ABCD bit encoding, but the MGX
8260 does not detect A/B signalling. Echo cancellation is enabled at set-up
unless a fax tone is detected.
3=bitOriented, applies to E1 Channel Associated Signaling
4=messageOriented, means Common Channel Signaling either on
channel 16 of an E1 line or channel 24 of a T1 line (reserved for future use)
XmitClkSource The clock source for the transmit signal:
1=Loop Timing, use the recovered receive clock
1
(reserved for future use)
2=Local Timing, use the local clock
3=Through Timing (reserved for future use)
