Port Rate
The Port Rate is less than or equal to the DDS Rate. The default values are 56K
for DDS I and 64K for DDS II. Table 4-6 shows the Port Rates for various modes
and formats.
Port Format
This field shows the data format for the DTE port which can be synchronous
(SYNC) or asynchronous (ASYNC). Asynchronous can be chosen only if one of
the TXP DDS modes is selected.
Port Mode
The DSU MP interface can operate in either of two modes: NON-TDM (standard)
and TDM (time division multiplex).
The DDS Mode must be set to either TXP-I or TXP-II to enable the TDM port mode.
NON-TDM (Port 1A, 2A, 3A, 4A, 5A, and 6A).
In the NON-TDM mode, DTE
interface B is disabled allowing DTE interface A to run at speeds up to the full
usable DDS line bandwidth as shown in Figure 4-15. This option is always
available.

Only one port (A or B) can be set to the highest rate at any given time. For example, if Port A is set to
the highest rate, Port B can be set no higher than the next highest rate.
