TDM Setup (MUX Funct: TDM) Configuration Options
Port Cntrl: Host
Next Host DSD Prev
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 B is enabled and a 6-port TDM is installed.
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 TDM or MCMP does not provide port contention.
DSD — Digital-Sharing Device (port contention). Controls CTS to ensure that only one port is active at
a time. (All ports must be configured for 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.
P1/2 FEPSh: Disab
Next Enab Disab Prev
Ports 1 and 2 FEP Port Sharing. Allows you to create an FEP port-sharing group consisting of Ports 1
and 2.
Enab
3
— FEP transmissions and controls pass through Port 1 into the multiplexer and also onto Port 2.
Data to be sent to the FEP is demultiplexed from the aggregate data stream or comes from
Port 2.
Disab — Disables the FEP port-sharing feature for Ports 1 and 2.
P3/4 FEPSh: Disab
Next Enab Disab Prev
Ports 3 and 4 FEP Port Sharing. Allows you to create an FEP port-sharing group consisting of Ports 3
and 4. This configuration option does not appear when a 2-port TDM/Flex is installed.
Enab
3
— FEP transmissions and controls pass through Port 3 into the multiplexer and also onto Port 4.
Data to be sent to the FEP is demultiplexed from the aggregate data stream or comes from
Port 4.
Disab — Disables the FEP port-sharing feature for Ports 3 and 4.
P5/6 FEPSh: Disab
Next Enab Disab Prev
Ports 5 and 6 FEP Port Sharing. Allows you to create an FEP port-sharing group consisting of Ports 5
and 6. This configuration option does not appear when a 2-port TDM/Flex is installed.
Enab
3
— FEP transmissions and controls pass through Port 5 into the multiplexer and also onto Port 6.
Data to be sent to the FEP is demultiplexed from the aggregate data stream or comes from
Port 6.
Disab — Disables FEP port-sharing feature for Ports 5 and 6.

When enabled, the CTS lead is forced ON (high) for the odd-numbered port.
