Figure 6-2 Physical Ports on Data-Only Models
The physical interfaces on data-only models of SmartSwitch 1800 are as follows:
●
The CSU/DSU port is RJ48C.
●
The LAN port, provided in two interface types, depends on the model:
◆
Ethernet – RJ48 (UTP, 10BaseT) and DB15F (AUI, 10Base5).
◆
Token Ring – RJ45 (UTP) and DB9F (STP).
●
WAN ports 0 and 1 are RS-232 DTE (male) and/or DCE (female), depending
on the attached Cabletron cables. (If the optional CSU/DSU port is used, WAN
port 1 is disabled.)
●
WAN ports 2 and 3 are determined by the attached Cabletron cables: RS-232,
V.35, and/or RS-449, all available as either DTE (male) or DCE (female).
●
WAN ports 4–7 exist on an optional expansion card, and are determined by the
type of card: V.35, RS-232, or RS-422 (which supports RS-449 interfaces, and
X.21 by special order).
