TDM MCMP Bridge
Async→Sync
Configure the port as asynchronous or
synchronous.

Async Rate Select an asynchronous rate for the port. X X

AsyncBit/Char Specify the length of the asynchronous
character, including the parity bit but
excluding the start and stop bits.

Stop Bits Specify the number of stop bits in the
asynchronous character.

Overspeed Specify the overspeed percentage for the
asynchronous DTE port.

RTS Cntrl For the port, select whether RTS is to be
Forced On or whether it is to follow the
external RTS lead.
X X X
TxCarrSel Enable the TDM or MCMP circuitry to
simulate switched-carrier operation used
by the V.13 protocol on an individual
channel; this operation is also called
pseudo-controlled carrier (PCC) mode.
X X Forced to
Const
RxCarrSel Enable the receiving DSU to look for V.13
codes on an individual channel that
indicate transitions of RTS at the remote
TDM or MCMP port; receiving DSU
toggles LSD, as appropriate.
X X Forced to
Const
PCC Buffer Enable a buffer to intercept the PCC code
on an individual channel so it is not
received by the receiving DTE.
X X Ignored
Elast Stor Enable the elastic store buffer (16-bit
register) for the port.
X X X
RTS/CTS Del For the port, select additional delay
between the time RTS turns ON and CTS
is turned ON.
X X X
DTR Alarm Enable the DSU to report a major alarm for
the port if the port’s DTR lead goes Off.
X X X
AntiStream Specify if the port is to be monitored for
streaming terminal alarms.

For MCMP mode, the values for configuration options Async→Sync, Async Rate, Async Bit/Char, and
Stop Bits are set at the control DSU and loaded into each tributary DSU when the Acquire Poll List (Acq)
command is issued from the control DSU’s DCP. Refer to the
MCMP Operation
section of Chapter 4 and
the
Poll List
section of this chapter.
