The 4T port adapter (see Figure 21) is currently available on the VIP-4R/4T, which has two port
adapter slots: port adapter slot 0 and port adapter slot 1. The 4T port adapter, installed in port adapter
slot 1, provides up to four synchronous serial interfaces. Each serial interface allows a maximum
bandwidth of 2.048 Mbps.

Synchronous Serial Overview

The 4T port adapter provides four channel-independent, synchronous serial ports that support
full-duplex operation at T1 (1.544 Mbps) and E1 (2.048 Mbps) speeds. Each port supports any of
the available interface types:  Electronics Industries Association/Telecommunications Industries
Association (EIA/TIA)-232, EIA/TIA-449, V.35, X.21, and EIA-530.

Note

Prior to the acceptance of the EIA/TIA standards by the ANSI committee, they were referred

to as recommended standards called RS-232 and RS-449.
