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	Ð	Select enable when interfacing with a DCE that receives clock from its own network source and does not
		support a Transmit Elastic Store.
Disab	Ð	Select disable if you do not have an extended network.

19.2 PowrLvl: +6

Next +6 0 ±10 Prev

19.2kbps 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	Ð	Select for DDS network service.
0	Ð	Select for an alternate DDS service.
±10	Ð	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 CCITT V.54 Loopback operation. V.54 sequences are generated and detected on Port 1.

Enab	Ð	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	Ð	Select disable if the DTE does not support V.54 loopback sequences, or the other DSUs do not support
		V.54 signaling.
