RS-232 DB-9 CONNECTOR

■Used to access the HDSL utilities menu tree via VT100 emulation software such as terminal, Hyper Terminal – Private Edition and ProComm Plus.

■Provision terminal port as follows:

HARDWARE SWITCHES

SW1

■Rotary switch sets the DSX-1 line build out

00 — sets LBO to 0-133 feet

1133 — sets LBO to 133-266 feet

2266 — sets LBO to 266-399 feet

3399 — sets LBO to 399-533 feet

4533 — sets LBO to 533-655 feet

Note: Positions 5,6 & 7 are not used.

SW2

Data Rate — 9.6 kbps, 19.2 kbps	■ Is used to provision the card. Default settings are in bold.
Asynchronous Data Format — eight data bits, no parity (none), one stop bit

	Hardware Flow Control should be disabled.	SW2-1	— sets the line code to either AMI or B8ZS
■		SW2-2	— sets the T1 framing to either Unframed or Framed
■	When using a PC with terminal software, be sure to disable any power saving programs.

Note: Unframed operation ignores the setting of SW2-3.
