Paradyne 6800 manual Digital, V54-remote-digital, Release

Modem/DSU Commands

NOTE

Aborting a Local Loopback from NMS on a tributary DSU requires using the tributary's internal DBM. A standby call must be established to the tributary to provide a path for the diagnostic information; since the tributary is in local loopback, it is no longer monitoring the DDS line. Since the only way to release a local loopback is through the DBM, the DSU will not go into local loopback unless a DBM is installed in the unit.

digital

This test loops back the received data path to the transmit data path at the digital interface internal to the modem.

DTE

This test is applicable only for 3400/4400 Series modems and 3600 Series DSUs equipped with TDMs.

For 3400/4400 Series modems, this test loops back the digital interface towards the DTE. The DTE transmit data lead is looped to the DTE receive data lead.

For 3600 Series DSUs, this test enables you to loop back the data path at the DTE/DCE interface on a per-port basis without affecting the operation of the remaining ports.

V54-remote-digital

This entry identifies the CCITT standard method for enabling a control modem to use the primary data channel to place a generic tributary modem

(V.54-compatible device) into a digital loopback state. For 3900 Series modems, this option is not supported.

release

This entry releases the device from a loopback state.

Port number (Required field)

Specify the port from which the test will be initiated.

For 3400/4400 Series modems in digital or DTE loopback state, valid entries are from 1 through 4.

For 3600 Series DSUs, valid entries are from 1 through 6, or a for aggregate (to loopback at the DSU instead of at the port).

For 3800/3900 Series modems, the only valid port number is 1.

For DATAPHONE II devices, the only valid port number is 1.

This test will disrupt the data transmission only on the specified port.

A pop-up menu is available listing valid selections. The default is 1.
