TDM Setup Configuration Options *
Port Cntrl: Host
Next Host DSD Prev
Port Control. Specifies how to handle contention between the ports in a digital-sharing group. This configuration option
appears 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 enforces 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 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; the lowest-numbered port has the highest priority.
Share DevB: Disab
Next Enab Disab Prev
Sharing Device B. Enabling this configuration option allows you to create a second digital-sharing group. Use Sharing
Device A with LPDA-2 enabled. 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.
Enab – Enables digital-sharing.
Disab – Disables digital-sharing.
Lowest Port#: 3
Next 1 2 3 4 5 Prev
Lowest Port Number. Select the lowest port number to be included in the digital-sharing group. This configuration option
appears when Sharing Device B is enabled and does not appear when a 2-port TDM/Flex is installed.
NOTE: Enabling Sharing Device B and accepting the defaults for configuration options Lowest Port Number and
Number of Ports in Group places Ports 3 and 4 in the digital-sharing group.
1 to 5 – Selects the lowest port number.
#Ports in Gp: 2
Next 2 3 4 5 6 Prev
Number of Ports in Group. Select total number of ports to be included in the second digital-sharing group. This
configuration option appears when Sharing Device B is enabled and does not appear when a 2-port TDM/Flex is
installed.
NOTE: 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, the port’s leads are
clamped until RTS is turned Off. (See
RTS Cntrl in Table 4-4.)
2 to 6 – Selects the number of ports.
* This table presents configuration options based on MUX Function set to TDM.
