What Is the 4R Port Adapter?

4R Port Adapter Receptacles, Cables, and Pinouts

A network interface cable provides the connection between the 9-pin Token Ring receptacles on the 4R port adapter and a media access unit (MAU). The 9-pin connector at the 4R port adapter end and the MAU connector at the network end are described in the section “Token Ring Connection Equipment” on page 8.

4R Port Adapter Cables

The Token Ring ports on the 4R port adapter are DB-9 (PC type) receptacles that require Type 1 or Type 3 lobe cables. Token Ring interface cables are not available from Cisco Systems, but are commercially available through outside cable vendors.

Type 1 lobe cables use shielded twisted-pair (STP) cable and terminate at the network end with a large MAU plug. (See Figure 6.) The 4R port adapter end of the cable is a DB-9 plug.

Type 3 lobe cables use either shielded or unshielded twisted-pair (UTP) cable and terminate at the network end with an RJ-11 plug. (See .) The 4R port adapter end of the cable is a DB-9 plug.
