Figure 2-2 Physical Port Locations on Data-Only Models

Table 2-2 lists all possible physical ports on data-only models of SmartSwitch 1800.

1

Physical interface, as described below.

Port 0 is RS-232.
Port 1 must be either RS-232 or DSU.
Ports 2 and 3 are determined by the attached cable: V.35, RS-232, or RS-449.
Ports 4–5 exist only if an optional expansion card is installed, 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).

Each cable is physical DTE (male connector) or DCE (female connector). Add a

T

or

C

to

the interface type to record this information. (This does not apply to a DSU or LAN port.)

2

The protocols that can be assigned to ports depend on the model of SmartSwitch 1800 and
the options that were purchased. All possible protocols are listed below:

Ports 0–7: Frame relay, X.25, SDLC, BSC Interactive, BSC Batch, Async.
LAN Port: IP, IPX, Bridge, LLC2.

Note that the LAN protocols (IP, IPX, Bridge, LLC2) are also assigned to physical frame
relay ports via interface records that map the protocols to the physical ports.

3

Only if the optional expansion card is installed.
