DSU Configuration Options
RxElasStor: Disab
Next Enab Disab Prev
Receive Elastic Store (only displayed when Full Mode is enabled). The DSU receives data using a receive data buffer on
the DSU’s received data (RXD) lead. This configuration option only supports single-port DSUs configured for disruptive
diagnostics (
Diag Type is set to Disr) and no rate adaption – when Rate(Kbps) is equal to PrtSp(Kbps). Both the control
and tributary DSUs must be configured the same.
Enab — Select enable when interfacing with a DCE that receives clock from its own network source and does not
support a Transmit Elastic Store.
Disab — Select disable if you do not have an extended network.
19.2 PowrLvl: + 6
Next + 6 0 –10 Prev
19.2 kbps Power Level (only displayed when Full Mode is enabled and when Rate(Kbps) is set to 19.2 kbps. This
configuration option selects the appropriate power level, in dBm, for operation at 19.2 kbps.
+ 6 — Select for DDS network service.
0 — Select for an alternate DDS service.
–10 — Select for LADS operation.
V.54 Lpbk: Disab
Next Enab Disab Prev
V.54 Loopback (only displayed when Full Mode is enabled). Used in point-to-point configurations, this configuration
option enables ITU-T V.54 Loopback operation. V.54 sequences are generated and detected on Port 1.
Enab — Select enable if the DTE generates V.54 loopback sequences, or if the DSU is communicating with a DSU
that is not a Model 3550 or 3551 that supports V.54
signaling.
Disab — Select disable if the DTE does not support V.54 loopback sequences, or the other DSUs do not support
V.54 signaling.
