Dial Modem Control Interface; Sdu Installation - Paradyne Compshere 3000 Series Installation Manual

COMSPHERE 3000 Series Carrier
4. Insert the other end of the wire to the next carrier's
E1 terminal, if any. Repeat Steps 2, 3, and 4 until
all the carriers are linked together.
5. Use a Phillips screwdriver to push the cap firmly
onto the terminal. As you seat the cap, the
terminal cuts through the insulation on the wires
and makes contact.
6. Insert the end of the wire coming from the alarm
and the end of a wire to be connected to the next
carrier into the E2 terminal, as described in Step 2.
7. Repeat Steps 3 through 5, connecting the E2
terminals instead, until all the carriers are linked
together.

Dial Modem Control Interface

Connectors J1 and J2 are defined in
Appendix A and provide an interface that can be used for:
D-lead control signaling. Directly supported.
Associates a signal lead with each modem.
Momentary connection of this lead to a common
ground activates the signal.
MI/MIC signaling. Supported by connecting all
MIC leads together and wiring them to Pin 25
(Signal Ground) on the corresponding J1 or J2
connector. Each MI lead can then be treated as a
D-lead connection. Provides two leads:
— Mode Indicate (MI)
— Mode Indicate Common (MIC) – usually via
Pins 3 and 6 of an 8-position modular VF
connector
Activation of the signal is by momentary connection of
these two leads. These two control signal methods are
identical in function. Activation causes the associated dial
modem to go off-hook in the Originate mode.

SDU Installation

An SDU is a circuit card designed for installation in the
slot at the extreme left end of the carrier (Slot 0). The
SDU is required for either or both of the following
conditions:
The devices in the carrier are to be controlled by an
NMS.
Multiple carriers in a cabinet configuration are to
be controlled from a single SDCP.
The SDU is not required for a single carrier:
Without an NMS interface or
With an SDCP installed.
