TDM Setup 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 appears if Sharing Device B is enabled and does not appear when a 2-port TDM/Flex 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 RTS off. Selection of the next port to transmit when more than one port has raised RTS
is based upon the port number; 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 2 – 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 2 – 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 2 – 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.
2 When enabled, the CTS lead is forced ON (high) for the odd-numbered port in the FEP port-sharing group.
