Port Connections 9

DDS The DDS network is connected through a standard RJ-48S (8-pin modular)

connector labeled DDS. The pinout assignments are displayed in Table 2-4.

In accordance with FCC Rules, Part 68.218(b), you must notify the telephone

company prior to disconnecting this product.

The network side of the PRISM 4101 is referred to as the network interface. This

interface contains an ALBO (automatic line build-out) allowing the unit to be

located a substantial distance away from the telco network interface with a receive

signal level down to -45 dB.

Maximum suggested cable lengths for the connections from the PRISM 4101 to

the network are listed in Table 2-5.Calculations are based on a cable temperature of

70°F, 0.083 µF/mile capacitance, a 45 dB loss at 7 km or 22 kft of 24 American

Wire Gauge (AWG) solid twisted plastic insulated cable (PIC).

RS-232 Data Port The RS-232 data port is a female, DB-25 connector that provides an RS-232

electrical interface. Pin functions for the interface are listed in Table 2-6.

Only one data port connection can be made at any given time. If the V.35 port is in

use, the RS-232 port unavailable.

FCC rules require that interconnecting cables carrying high speed data be shielded

appropriately in order to minimize radio frequency interference.
