7.5.10 Modem Guidelines
Review the following guidelines before wiring a network with modem media boards.
• Modem media wiring for NICs applies to non-4100ES/4100U systems only.
• Phone Line Classification consists of the following:
- Private leased line for analog data communications
- No dial tone
- Full duplex operation
- No conditioning required
- No signaling required
- Two-wire line interface
- RJ-11 modular jack
• If a four-wire circuit is required, the line must include a data station termination (DST) device to provide the two-wire interface
required by the 4120 network modem. The DST device should be located as close to the FACU as possible to minimize dry line signal
losses.
• The modem is capable of full duplex V.32bis analog data communications. The transmit signal level is 10 dbm.
• Telecommunications device: Xecom Model XE1414 or XE1414C V.32bis Two-Wire Analog Modem
• Modem FCC Registration Number: DWEUSA-75322-FA-E (565-279); DWEUSA-35610-M5-E (566-338)

Modem Wiring

Important:
Modem media wiring for NICs applies to non-4100ES/4100U systems only.
The Modem Media Card uses RJ-11 connectors to connect 4100-6078 NIC Assemblies across parts of a network.
Use the RJ-11 connector (P2) to connect nodes that use the modem media card. Do not use connector P1 (P1 is reserved for when the
daughter card is used as a physical bridge). Leased lines must be analog, full-duplex, private line (no dial tone), with a two-wire RJ-11
interface. Class B requires one circuit; Class X requires two circuits.

Wiring Illustrations

The following figures show how to wire the NIC. The illustrations use the 565-274 and 565-275 motherboards only. If you are using the
4100ES motherboard, refer to Figure 55 along with the figures below.
