DSX-1 BANTAM JACKS

EQ

■Provides an intrusive access point to the data stream.

TX - Access the data stream being received from the network. RX - Access the data stream being transmitted to the network.

MON

■Provides a non-intrusive access point to the data stream.

TX - Monitors the data stream being received from the network RX - Monitors the data stream being transmitted to the network.

NOTE: The DDM+ H2TU-C does not have the DSX-1 Bantam Jacks option.

RS-232 DB-9 CONNECTOR

■Used to access performance monitoring data, perform loopbacks and provision units via VT100 emulation applications such as Hyper Terminal – Private Edition, ProComm Plus, and Telnet.

■There are two types of terminal emulation modes, Manual and Real-Time. Use “CTRL-T” to toggle between the two modes.

Manual Emulation Mode: Press the space bar 3 times to manually update the screen. Print screen and log file commands are available in this mode.

Real-Time Emulation Mode: The default mode. Print screen and log file commands are not available in this mode. Cursor placement and screen highlighting are enabled.

■Provision terminal port as follows:

Data Rate — 1.2 to 19.2 kbps

Asynchronous Data Format — eight data bits, no parity (none), one stop bit

■When using a PC with terminal software, be sure to disable any power saving programs.

PROVISIONING NOTES

■This unit can be provisioned via the RS-232 port or remotely via ITS codes. This unit cannot be provisioned from the faceplate four-character display. Select “2” from the ADTRAN HDSL2 Main Menu Screen to view the Provisioning Screen.
