Configuration

System Status

With this option on, RLSD must be on for DSR to be on. This means
that DSR will turn off while receiving Idle or Out-of-Service codes.
With this option off, DSR does not depend on the state of the DDS/
MR64 receiver. This option can be used when the remote DDS/MR64
maintains a permanent RTS to verify a complete link.

Circuit Assurance

When on, RLSD must be on for CTS to be on. This means that CTS will
turn off while receiving Idle or Out-of-Service codes. When this option
is off, CTS does not depend on the state of the DDS/MR64 receiver.
This option can be used when the remote DDS/MR64 maintains a
permanent RTS to verify a complete link before sending data.
Note
When using DDS/MR64 units for multi-point links, the
master unit must have both the CA and SS options disabled.

RTS/CTS Delay

Certain applications and DTE devices require longer RTS-CTS delay
times than others. The approximate RTS on to CTS on delay time selec-
tions are:
• 25 ms
• 30 ms
• 60 ms
• Normal - The delay is dependent on the rate. Refer to Table 3-3.

64 k Scrambler

In 64 k clear channel operation, certain specific long patterns of data
may be interfered with by the DDS network. Should this occur, the 64 k
Scrambler option should be enabled. When the 64 k Scrambler option is
enabled, the remote DSU/CSU must be a Motorola DDS/MR64 product
with the 64 k Scrambler option enabled.
