EIA-530 Connections

EIA-530, which supports balanced transmission, provides the increased functionality, speed, and

distance of EIA/TIA-449 on the smaller, DB-25 connector used for EIA/TIA-232. The EIA-530 standard

was created to support the more sophisticated circuitry of EIA/TIA-449 on the existing EIA/TIA-232

(DB-25) hardware instead of the larger, 37-pin connectors used for EIA/TIA-449. Like EIA/TIA-449,

EIA-530 refers to the electrical specifications of EIA/TIA-422 and EIA/TIA-423. Although the EIA-530

specification recommends a maximum speed of 2 Mbps, EIA-530 is used successfully at 4 Mbps or

faster speeds over short distances (2-Mbps in the 2T16S network processor module).

The EIA-530 adapter cable is available in DTE mode only. The network end of the EIA-530 adapter

cable is a standard DB-25 plug commonly used for EIA/TIA-232 connections. Figure 15 shows the

DB-25 connector at the network end of the adapter cable.

V.35 Connections

The V.35 interface is recommended for speeds up to 48 kbps (although in practice it is used successfully

at 2-Mbps in the 2T16S network processor module).

The network end of the V.35 adapter cable provides a standard 34-pin Winchester-type connector, as

shown in Figure 16. V.35 cables are available with a standard V.35 plug or receptacle in either DTE or

DCE mode.
