DSU Configuration Options
64KScramblng: Off
Next On Off Prev
64 kbps Scrambling. Controls the data scrambler used with 64 kbps Clear Channel operation. Data
scrambling suppresses the possible simulation of network control codes by application data. This
configuration option only appears when Rate(Kbps) is set to 64CC. This configuration option must be the
same at both the local and remote DSUs.
On — Enables data scrambling.
Off — Disables data scrambling.
64KLatchLpbk: On
Next On Off Prev
64 kbps Latching Loopback. Controls the DSU’s response to the network latching loopback sequence on
64
kbps Clear Channel operation. This configuration option only appears when Rate(Kbps) is set to 64CC.
On — DSU responds to the network latching loopback command. ON is required for compliance with
AT&T Technical Reference 62310 – 1987.
Off — DSU ignores the network latching loopback command.
AggrSwitch: Disab
Next Enab Disab Prev
Aggregate Switch.
5
When this configuration option is enabled, the DSU bridges aggregate data to one of the
Port 1 interfaces. If the DTE Port configuration option in Table 6-6, General Configuration Options , is set to
EIA232, the aggregate data is bridged to the V.35 interface; if the DTE Port configuration option is set to
V.35, the aggregate data is bridged to the EIA-232 interface.
Enab — Enable this configuration option for aggregate switch backup.
Disab — Disable this configuration option if you are using another backup method.
AgSw Timing: Aggr
Next Int Aggr Prt1 Prev
Aggregate Switch Timing.
6
If Aggregate Switching is enabled and the DSU is commanded to perform a
backup from the DCP or NMS, this value determines where timing is taken from during dial backup.
Int — Timing is taken internally from the unit.
Aggr — Timing is taken from the network.
Prt1 — Timing is taken from the port. These selections are not available in MCMP mode.
V.54 Lpbk: Disab
Next Enab Disab Prev
V.54 Loopback. Enables CCITT V.54 Loopback operation. This configuration option is supported for
point-to-point configurations. The V.54 sequences are generated and detected on Port 1.
Enab — This configuration option should be enabled if the DTE generates V.54 loopback sequences or
if the 3600 Series DSU is communicating with a non-AT&T DSU that supports 54
signaling.
Disab — This configuration option should not be enabled if the DTE does not support V.54 loopback
sequences or other DSUs do not support V.54 signaling.

If a DBM is installed, it must be disabled in order to select this configuration option. If a DBM is installed, it must be disabled in order to select this configuration o tion.
6
When not in TDM mode, this configuration option only displays Port 1.
