DSU Rate .
Data rate (in kbps) on the digital circuit. Must be set to match the speed of the DDS circuit.
64CC — 64 kbps Clear Channel (on a 72 kbps circuit) with 3600 Series DSUs at both ends of the circuit.
64L — 64 kbps LADS operation.
NOTE: The control and tributary DSUs must be set to the same value.

Port Speed . Sets the speed of the DTE port interface. The port speed may be set to any value less than or
equal to the Rate(Kbps) configuration option value. If the value is set less than the DDS rate, the DSU
performs rate adaption.
64 — Select the DTE's port speed. The following port speeds do not appear in MCMP mode: 64, 56,
to 1.2 32, 28.8,18.8, 18.0, 9.2, 8.4, 4.4, 4.0, and 2.0.
Disab — Disable port speed.

Transmit Clock Source .
Int — Internal clock source. Timing is taken from the DSU.
RXC — Receive clock source. The DSU generates its transmit timing from the receive data signal. This
choice is provided for LADS configurations. It differs from the DDS selection during tests.
Ext — External clock source. The DSU is timed by the external Transmit Timing lead on Port 1 only.
Ports 1 — 6. The DSU is timed by the external Transmit Timing lead on the specified to
Prt1 to —
Prt6 port.
DDS — DDS Network. This source is used when the DSU is connected to a DDS network and the
network provides the timing.

If operating in MCMP mode (MUX Funct is set to MCMP), the Rate(Kbps) default is 56.

Port speed does not appear if TDM or MCMP hardware is installed and MUX Funct is set to TDM, MCMP,
EBrdg, or CBrdg. Instead, this entry is made in the Port Speed (PrtSp) Configuration Options for DSU with
TDM (Table 6-14) or the Port Speed (PrtSp) Configuration Options for DSU with MCMP
Configuration Options Tables

In TDM and MCMP mode, the Ext clock source is replaced with Prt1, Prt2, Prt3, Prt4, Prt5, Prt6. Selecting a
port setting means that the TDM will operate with timing provided by the DTE at the designated port
(EIA-232 Pin 24 or V.35 Pins U and W).
For CBrdg mode in full backup and EBrdg mode, timing is set using the Bridge Timing configuration option
in Table 6-11, Digital Bridge Setup Configuration
