Supported Physical Interfaces
The WSX family of products support numerous physical interface (port) types. The port types
available with the WSX family are:
Universal Serial Port
The Universal Serial Port (USP) provides connectivity to legacy synchronous serial port
devices. With the addition of an adapter cable, it supports RS-232, RS-449, RS-530, V.35 and
X.21 Data Terminal Equipment (DTE) and Data Carrier Equipment (DCE) interfaces at speeds
up to 2.048 Mbps. USPs support access via Frame Relay or synchronous PPP. The WSX
automatically detects the cable type connected and will configure the correct physical
interface to use.
ISDN Basic Rate Interface Port
The ISDN Basic Rate Interface (BRI) port supports either a U or S/T interface (jumper
selectable) for interfacing to public or private ISDN networks. Synchronous PPP is supported
on the two bearer (B) channels. Multiple ISDN switch protocol variations are supported on
the delta (D) channel (used for signaling). Each B channel runs at 64 kbps, and the D channel
runs at 16 kbps.
Fractional T1 Port
The fractional T1 port connects directly to North American and Japanese circuit switch digital
data public or private networks without requiring an external Digital Service Unit/Channel
Service Unit (DSU/CSU). The port provides an integral DSU/CSU function with both short-
haul (i.e,. short distance) and long-haul (i.e,. long distance) capabilities. The port allows the
user to configure a range of time slots from 1 to 24 time slots used to allow for full T1 (all 24
time slots used) or a fractional T1 (less than 24 time slots) service. The fractional T1 port can
support access via Frame Relay or synchronous PPP.

Note
♦
For public digital networks, check with your service
provider. They may allow only connections that use a
configured short-haul interface via a network-provided
Channel Service Unit (CSU).
Fractional E1 Port
The fractional E1 port connects directly to ITU-T standard circuit switch digital data public or
private networks without requiring an external DSU/CSU. The port provides an integral
DSU/CSU function with both short-haul (i.e., short distance) and long-haul (i.e., long
distance) capabilities. The port allows you to configure for full E1 (all 30 or 31 time slots
used) or fractional E1 (1-29 time slots) service. The fractional E1 port supports access via
either Frame Relay or synchronous PPP.

configured short-haul interface via a network-provided
