Connecting the PRI
The SmartNode comes with one or four PRI ports. These ports are usually connected to a PBX or switch (local
exchange (LE) ). Each PRI T1/E1 port is a RJ-48C receptacle. In most cases, a straight-through RJ-45 can be used
to connect the PRI. Each port can be configured as NT (clock master) or TE (clock slave).

For details on the PRI port pin-out and ISDN cables, refer to Appendix C, “Cabling” on page 43 and Appen-
dix D, “port pin-outs” on page 47.

Connecting the 10/100/1000Base-T Ethernet LAN and WAN cables
The SmartNode 4950 has automatic MDX (auto-crossover) detection and configuration on all Ethernet ports.
Any of the ports can be connected to a host or hub/switch with a straight-through or cross-over wired cable.

1. Connect to the subscriber port of the broadband access modem (DSL, cable, WLL) to ETH 0/0.

Note

The SmartNode Ethernet ports operate in Full Duplex mode only. Do not
connect to Half Duplex ports. For best results, use auto-negotiation. Auto
negotiation is mandatory when using 1000BaseT (Gigabit) Ethernet.

2. Connect port ETH 0/1 to your LAN.

Installing the DSL WAN cable. The SmartNode Model 4950 comes with an option for a G.SHDSL WAN
interface. Use a straight-through RJ-11 cable to connect the G.SHDSL port.

For details on the Ethernet port pinout and cables, refer to

Appendix C, “Cabling”

The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.
