Reset
Reset causes the modem to stop operation and
perform a complete program restart. The modem begins
the power-up test sequence that ends with the Top-Level
menu displayed on the LCD. Configuration options
stored in an Active (Saved) configuration area are copied
to the Active (Operating) configuration area.
Make Busy or Remove Make Busy
The Make Busy function is available only on 3821-B1
models.
The Make Busy function forces the modem off-hook
so it cannot answer a call. This is often used with PBX
systems to permit the busy out of a PBX port for rotary
or hunt groups.
WARNING
To not violate FCC and DOC
regulations, this function must
only be used behind a user’s
PBX.
Service Line or Disconnect Service Line
The Service Line function is available only on
3821-B1 models.
The Service Line function allows you to switch a
specific 3821Plus modem installed in a COMSPHERE
3000 Series Carrier from normal dial operation to
service-line operation. This switch only places the
modem on the service line. For a connection to be
established, you must still use the normal dialing
methods as described earlier in this chapter under Call
Setup Branch (page 3-9).
A service line is an extra dial line connected to a
COMSPHERE 3000 Series Carrier. This line is normally
shared by up to eight 3821Plus cards (24 modems)
installed in either Slots 1–8 or Slots 9–16. However, by
daisy chaining the service-line connector of one Network
Interface Module (NIM) to the service line of another
NIM installed in the same carrier, you can permit all
16 cards (48 modems) to share one service line. The
service line can also be extended to other carriers in a
cabinet. Only one modem may be switched to the service
line at a time. For more information regarding daisy
chaining of modems to the service line, refer to the
COMSPHERE 3000 Series Carrier, Installation Manual.
