2-4 Installation

PRISM 4151

NET

The DDS network is connected through a standard RJ-48S

(8-pin modular) connector labeled NET. The pinout assign-

ments are displayed in Table 2-F.

In accordance with FCC Rules, Part

68.218(b), you must notify the tele-

phone company prior to disconnecting

this product.

The network side of the CSU/DSU is referred to as the net-

work interface. This interface contains an ALBO (automatic

line build-out) allowing the CSU/DSU to be located a sub-

stantial distance away from the telco network interface with

a receive signal level down to -45 dB.

V.35

The PRISM 4151 is equipped with a V.35 data port (on a

standard 34-pin connector). Pin functions for the high speed

port interface are listed in Table 2-G.

FCC rules require that interconnect-

ing cables carrying high speed data

be shielded appropriately in order to min-

imize radio frequency interference.

Network Management

Network management is accomplished via the SUPV port

(page 2-3), SLIP port (page 2-3), or the LAN port (page 2-2).

The PRISM 4151 incorporates the full TCP/IP stack and

supports inbound T

ELNET

. It has an embedded SNMP agent

supporting the TxPORT enterprise MIB, which provides

access to the specific functionality of the CSU/DSU, includ-

ing DDS status information. MIB objects for the PRISM

4151 are listed in Appendix C.

Power Connection

AC powered units use a 110 VAC captive power supply.

There is no power switch. The green power LED on the

front panel illuminates after the LED initialization sequence

ends. If the indicators do not illuminate, recheck the power

connections and the primary AC circuit breaker.
