digital-sharing group. This configuration option is displayed only if Sharing Device A is enabled.
Enabling Sharing Device A and accepting the defaults for configuration options Lowest Port Number and
Number of Ports in Group places Ports 1 and 2 in the digital-sharing group.
Individual ports in a digital-sharing group can be configured for streaming terminal. If streaming terminal
detection is enabled on a port and RTS for that port is ON longer than the value selected for that port, the
port's leads are clamped until RTS is turned Off.
2 to 6 — Selects the number of ports. This configuration option does not appear when a 2-port
TDM/Flex is installed.

Port Control . Specifies how to handle contention between the ports in the second digital-sharing group.
This configuration option is displayed only if Sharing Device A is enabled.
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.
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.

Sharing Device B .
Enabling this configuration option allows you to create a second digital-sharing group.
This configuration option does not appear when a 2-port TDM/Flex is installed. The following rules apply:
All ports in a group must have the same port speed.
All ports must be adjacent.
A digital-sharing group can have from 2 to 6 ports.
All ports must be assigned to the same channel.
Enab — Enables the digital-sharing feature.
Disab — Disables the digital-sharing feature.

For MCMP, a digital-sharing group is set up by assigning multiple ports to the same channel. If DSD
contention is required, these sharing device configuration options must also be used. Only two
digital-sharing groups may have DSD contention; all other groups are defaulted to Host contention.

For an LPDA-2 configuration, only Sharing Device A can be used to create a digital-sharing group.
