TDM/MCMP Port (MUX Funct: TDM or MCMP) Configuration Options*
RTS/CTS Del: 0
Next Chang Prev
Request-To-Send to Clear-To-Send Delay . Allows for an additional delay between the time that RTS is
turned ON and CTS is turned ON. An additional delay is sometimes required for multiplexed applications
operating in switched-carrier operation with primary channel extended circuits. This configuration option
must provide enough delay so that the last DSU in the circuit has time to train and is ready to accept data
before CTS is turned ON.

Chang — Set the RTS-to-CTS delay to the desired value, from 0 to 1040 milliseconds in 8 milliseconds
increments.
DTR Alarm: Disab
Next Enab Disab
Data Terminal Ready Alarm . Causes the DSU to report an alarm for the port if the port's DTR lead is Off for
more than 30 seconds. The DCP displays DTR Alarm and reports the alarm to NMS.
Enab — If the port's DTR lead turns Off for 30 seconds, the DSU reports an alarm.
Disab — Regardless how long the port's DTR lead is Off, no alarm is reported.
AntiStream: Disab
Next Chang Prev
Antistreaming . Specifies if the port is monitored for streaming terminal alarms. The purpose of antistreaming
is to provide network protection against a streaming DTE (a defective DTE that has its RTS lead constantly
turned ON) by disabling the DTE.
If the DTE turns ON RTS longer than the time specified for the AntiStream configuration option, the tributary
DSU turns ON its alarm indicator and clamps the port's leads until RTS is turned Off. Although the DTE port
is not allowed to send, it is capable of being tested or disabled. A test resets the streaming terminal timer.
When the test is completed, the timer starts again.
Upon detecting that RTS is no longer turned ON, the DSU turns Off its alarm and resets the streaming timer,
and allows the DTE port to send data once again.
At tributary locations, this configuration option is generally used for digital-sharing operation and for MCMP
operation. This configuration option has an effect only at a port configured with RTS Control set to DTE. It is
not allowed when RTS Control is set to FrcOn.
Chang — Set timer to any value from 1 to 100 seconds in increments of 1, or Disab. Incrementing the
value when it reaches 100 disables this configuration option. When using async terminal, enter
0 (zero) to disable.
DSR FrcOn: Disab
Next Enab Disab
Data Set Ready Forced On . Overrides any other options controlling the Data Set Ready lead.
Enab — DSR remains ON as long as the DSU is working, regardless of tests and network alarms.
Disab — DSR functions as an active lead reflecting various test and alarm conditions and other options.

Port speeds of 38.4 and higher can only use delays of up to 504 milliseconds.
* The menu paths for Port 1 through Port 6 are identical.
