Digital Bridge Port (MUX Funct: CBrdg or EBrdg) Configuration Options*

RTS Cntrl: DTE
Next FrcOn DTE
Request-to-Send Control . Controls the behavior of the internal RTS lead.
FrcOn — This configuration option should not be enabled in Bridge mode.
DTE — DSU turns ON RTS when the external RTS is turned ON. CTS is turned ON or Off by the
external control signal RTS. Choose this configuration value for Bridge mode.
TxCarrSel: Const
Next Const Cntrl
Transmitter Carrier Select . This configuration option is ignored in Bridge mode.
RxCarrSel: Const
Next Const Cntrl
Receiver Carrier Select . This configuration option is ignored in Bridge mode.
PCC Buffer: Disab
Next Enab Disab
Pseudo-Controlled Carrier Buffer . This configuration option is ignored in Bridge mode.
Elast Stor: Disab
Next Enab Disab
Elastic Store . Elastic Store hardware consists of a transmit buffer (register). Serial data from the extended
circuit is clocked into the DSU elastic store using a clock (on EIA-232-D Pin 24 or V.35 Pins U and W)
provided by the extended circuit received clock lead (on Pin 17). The DSU uses its own system timing to
clock data out of the buffer.
Elastic Store is reset on power-up, overflow, or after the request-to-send lead makes an Off-to-ON transition.
After reset, the elastic store can drift by 8 bits before overflow occurs.
Enab — Enable this configuration option if you have an extended network.
Disab — Disable this configuration option if you do not have an extended network.
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. This is useful for multiplexed applications operating in switched-carrier
operation with primary channel extended circuits. This configuration option must provide enough delay so
that the last modem 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 millisecond
increments).
* For the DCE port (first port of the digital bridge), the Elastic Store is automatically enabled and RTS Control is
automatically set to =DTE. All other configuration options for the DCE port are turned Off. The menu paths for
Port 2 through Port 6 are identical.
