Introduction

MN/CDMQx.IOM

1.2.4Data Interfaces

The Modem can be ordered with a number of interfaces. Each data interface can operate on a Modulator or Demodulator. This allows the user to exchange interface cards for different applications. The interfaces offered include:

EIA/TIA-530

(EIA-422) DCE (at rates up to 12 Mbps)

V.35 DCE (at rates up to 12 Mbps)

G.703 Balanced T1 & E1 (DB-15) with D&I

G.703 Unbalanced T1 & E1 (BNC)

EIA/TIA-612/613 HSSI (50-pin SCSI connector, to 20 Mbps)

1 to 4 Ports of G.703 (E1 with D&I ) Quad E1 Interface Card, (DB-9F)

1.2.5Turbo Product Coding

The Modem offers optional 2nd generation Turbo Product Codec (TPC). TPC simultaneously offers increased coding gain, lower decoding delay, and significant bandwidth savings. The TPC provides:

BPSK 5/16 and 21/44

QPSK 21/44, 3/4, 7/8 and 17/18

8-PSK 3/4, 7/8, and 17/18

16-QAM 3/4 and 7/8

1.2.6Remote Control

The operator may configure and monitor the modem from the front panel, or through the remote M&C port. M&C is via RS-232, RS-485 (2/4 wire) or 10/100 BaseT Ethernet.
