Modem Guidelines
• Modem media wiring for NICs applies to non-4100U/4100ES 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
• 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-4100U/4100ES systems only.
The Modem Media Card uses RJ-11 connectors to connect 4100-6014 and 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.
