Field Descriptions

All fields (programmable and read-only) are grouped in frames based on their
function.

Channel Setup

Channel
Allows DS0 channel assignment to the selected VF line. Channel
number is selectable from 1 to 24. A '-' (default selection) indicates
that a channel has not been assigned. Each channel occupies its
own DS0 (64 kb/s) time slot on the JVT.
Ensure that the channel(s) assigned on this unit are not assigned
on any other DS0 level unit on the same JVT. The corresponding
far-end unit interface must be given the same channel assignment.
Note: The channels assigned to the two VF lines do not have to be
consecutive.
PCM Companding
Sets the companding law applied in the A/D converter. The µ-law
is used in North America and Japan. A-law is used in Europe and
the rest of the world.

Signalling Setup

Signalling Type
May be set to Loop Start (LS), Ground Start (GS) or Private Line
Automatic Ringdown (PLAR). The far-end unit interface must be
set for the same signaling type.
Note: Although the 86445-32 2W FXS unit is normally used with
either 86445-41 2W FXO unit (for LS and GS applications) or
86445-3X 2W FXS unit (for PLAR application) at the far end, it can
also be used with an 86444 4W VF unit when no signaling is
required. This may be utilized for VF channel testing.
Ringing Duration
Sets the ringing duration when in PLAR mode. May be set to 10
sec, 20 sec, 60 sec and Indefinite.
Note: This field is active only if PLAR is selected in the Signalling
Type field.
Note: In the Loop Start (LS) and Ground Start (GS) signaling
modes the ringing duration is not limited.
