MCMP Setup (MUX Funct: MCMP) Configuration Options
Lowest Port#: 1
Next 1 2 3 4 5 Prev
Lowest Port Number.
1
Allows selection of the lowest port number to be included 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.
1 to 5 — Selects the lowest port number.
#Ports in Gp: 3
Next 2 3 4 5 6 Prev
Number of Ports in Group. Allows selection of the total number of ports to be included in the digital-sharing
group. This configuration option is displayed only if Sharing Device B is enabled and a 6-port TDM is
installed.
Enabling Sharing Device B 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.
Port Cntrl: Host
Next Host DSD Prev
Port Control.
1
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.
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.
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.
This configuration option will not display if MUX is set to None.
Enab
3
— FEP transmissions and controls pass through Port 1 to be broadcast onto the aggregate data
stream and to Port 2. Data to be received by the FEP comes from both the aggregate data
stream and Port 2.
Disab — Disables the FEP port-sharing feature for Ports 1 and 2.
1
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.
3
When enabled, the CTS lead is forced ON (high) for the odd-numbered port.
