Note
: The unit's yellow (BUSY) LED illuminates only if an OFF-
HOOK condition is initiated from an external source (i.e. signaling
test set or telephone).
Note:
The signaling information is mapped into two bits of the
PSFR byte (part of VT1.5 frame). There are four possible transmit
signaling combinations that can be addressed by these bits: 00, 01,
10, and 11 and some of them are not used. When a NOT VALID
signaling condition (combination of the two bits) is selected, the unit
will send the selected combination even though it does not apply to
any valid signaling condition for the Signalling Type chosen.
RECEIVE SIGNALLING
Allows the user to set a specific signaling condition that will be sent
to the local drop equipment and is used for test/maintenance
purposes only. The options available depend on the
Signalling
Type
selected (see
Signalling Setup
window). The selected
signaling condition overrides the actual signaling condition received
from the far-end unit only if RECEIVE SIGNALLING field in the
SIGNALLING SETUP window is set to TEST mode.
Talk Battery and Ringing Generator
SOURCE (Not Adjustable)
Displays INTERNAL.
VOLTAGE
[V]
Selectable for -28 or -56 V. This is the talk battery voltage that this
unit's sub-board will provide to the line (if installed).
Note
: On units configured for 600
Ω
resistive only, it is
recommended that -56 VDC not be used.
RING CADENCE TYPE (Available in PLAR mode only)
Sets the type of ringing produced when in PLAR mode. May be set
to NORTH AMERICAN, EUROPEAN or STEADY.
Note:
This field is displayed only if PLAR is selected in the
SIGNALLING TYPE field (SIGNALLING SETUP window) and the
unit's Micro code is version 2.5 or later.
