Table 2. Synchronous Data Port Options (1 of 2)
8775-A2-GZ40-10
Port Status
Possible Settings: Enable, Disable
Default Setting: Enable
Determines whether the port can be configured and used.
Payload Rate
Possible Settings: 64, 128, 192, 256, 320, 384, 448, 512, 576, 640, 704, 768, 832, 896,
960, 1024, 1088, 1152, 1216, 1280, 1344, 1408, 1472, 1536, 1600, 1664, 1728, 1792,
1856, 1920, 1984, 2048
Default Setting: 128
NOTE: Payload rates of 1088 kbps and higher pertain only to the 2 Mbps
termination unit.
Specifies the payload rate of the port.
Transmit Clock Source
Possible Settings: Internal, External
Default Setting: Internal
Specifies whether the transmitted data for the synchronous data port is clocked using
an internal clock provided by the 8775 Termination Unit (synchronized to the clock
source specified by the clock source configuration option) or an external clock provided
by the DTE connected to the synchronous data port. If an external clock is used, it must
be synchronized to the same clock source as the 8775 Termination Unit.
Invert Transmit Clock
Possible Settings: Disable, Enable
Default Setting: Disable
Specifies whether the clock supplied by the 8775 Termination Unit on the TXC
interchange circuit DB (CCITT 114) is phase inverted with respect to the Transmitted
Data interchange circuit BA (CCITT 103). This configuration option is useful when long
cable lengths between the 8775 Termination Unit and the DTE are causing data errors.
Send All Ones on Data Port Not Ready
Possible Settings: Both, Disable, DTR, RTS
Default Setting: Both
Specifies the conditions on the data port that determine when valid data is not being
sent from the DTE. When this condition is detected, all ones are sent to the network.
Action on Network LOS Alarm
Possible Settings: Halt, None
Default Setting: Halt
Specifies the action taken on the synchronous data port when an LOS (Loss Of Signal)
alarm is received on the network interface.
Network Initiated Data Channel Loopback
Possible Settings: Disable, Enable
Default Setting: Disable
Allows the initiation and termination of a Data Channel Loopback (DCLB) by the receipt
of a DCLB-actuate sequence or DCLB-release sequence from the network or far-end
device.
