Switched Mode

WITCHED

mode is used to multiplex several remote extensions (up

to 40) to two host ports. This enables many remote users to have

access to a limited number of access lines on a call-by-call basis.

The host unit typically connects two extensions to a PBX via an

FXO module. The remote units connect to telephone sets via FXS

modules. See the section Switched Mode Application on page 5-9 for

an example application.

Direct Mode

IRECT

mode is used to accomplish a one-to-one mapping of ports

across a frame relay network. In this mode,

and

on the local

unit are connected to

and

on the remote unit. With this

option, one or two extensions can be extended across the frame

relay or DDS network by using an FXO module on the local unit

and an FXS module on the remote unit. PLAR circuits are also

supported by using FXS modules on both ends of the circuit.

Related application examples are given on pages 5-12 and 5-13.

Remote/Host (Rem/Host)

Configure the unit to be either a

EMOTE

unit or a

OST

unit. There

must be only one

OST

unit in a switched environment. Typically,

the

OST

unit connects to the PBX via FXO connections. The

OST

unit maintains all of the extension/DLCI information. All units

other than the

OST

are set up as

EMOTE

units. No DLCI or

extension configuration is required for

EMOTE

units.

DLCI Mapping (DLCI MAP)

The options for

DLCI M

vary depending on the

ODE

and

EMOTE

OST

selections.

This option is available only when the

ODE

is set for
