Digital Bridge Setup (MUX Funct: CBrdg or EBrdg) Configuration Options *
Port Cntrl: Host
Next Host DSD
Port Control . Specifies how to handle contention between ports in a port-sharing group. This configuration
option is only displayed if Sharing Device A is enabled.
In multipoint dial backup, ports are not automatically dropped from the digital bridge if the backup call is lost.
A DBM that has dropped a backup call will no longer be raising RTS at the digital bridge port, and is
effectively isolated from the digital bridge. If the backup call was dropped due to a network problem and a
new call is successful, the DBM is able to raise RTS and again work with the digital bridge.
Host — No port contention. Causes CTS to turn ON for any port that has RTS turned ON, even if
another port is active (RTS ON). The host protocol must enforce the order of transmission to
avoid collisions. The connected DBM-V, DBM-S, or DBM-D is not required to have
V.13 switched-carrier emulation. In CBrdg mode, this is the only available option if Diag Type is
set to NonD. In EBrdge mode, this should be used if the extended bridge is connected to an
MCMP control or a nondisruptive central-site bridge.
DSD — Digital-Sharing Device (port contention). Controls CTS to ensure that only one port is active at
a time. (All ports must be configured with RTS Control set to DTE.) A subsequent DTE that has
RTS turned ON does not have its CTS turned ON until the first DTE has lowered its RTS.
Selection of the next port to transmit when more than one port has a raised RTS is based upon
the port; the lowest-numbered port has the highest priority.
Share DevB: Disab
Next Disab Prev
Sharing Device B . Allows you to create a digital-sharing group to configure for contention.
Disab — This configuration option is Forced Off (disabled) in Bridge mode so no selection is required.
* Selections in bold are the factory-set (default) configuration options stored in FacB.
