OPTION DESCRIPTIONS

Speed

Duplex

Data Inversion

These options are explained in the following sections. For
information on setting the options, refer to Chapter 3, ''Using the
Front Panel.''
Settings: 56KBPS, 64KBPS
The speed option allows you to set the data rate for the V.35
interface. The speed must match the speed of the local V.35
terminal equipment.
Set the SPEED option to 56KBPS if you want the HSL to transmit
and receive data across the V.35 interface at 56 Kbps.
Set the SPEED option to 64KBPS if you want the HSL to transmit
and receive data across the V.35 interface at 64 Kbps.
Settings: FULL, HALF
The duplex option is used only when the HSL is operating at 56
Kbps.
If you set the DUPLEX option to FULL, the HSL ignores the
Request to Send input lead and holds the Clear to Send output
lead ON while in the data mode.
If you set the DUPLEX option to HALF, the HSL monitors the
Request to Send input lead and does not turn on the Clear to Send
output lead until it is in the data mode and the Request to Send
input lead is ON.
Settings: ON, OFF
The data inversion option is used only when the HSL is operating
at 64 Kbps, and transmitting data over restricted facilities using
HDLC-based protocols.
Set DATA INVERSION to ON for compatibility with the
ACCUNET MPDMs.
Set DATA INVERSION to OFF when data inversion is not needed
(for example, compatibility with ISDN and DSU endpoints).
