daughtercard supports one voice channel, using either an analog FXS or FXO
interface. Both interfaces use RJ11 connectors.
Dual FXS Voice
Relay
Daughtercard
The Dual FXS Voice Relay Daughtercard provides two FXS interface ports and
support one voice channel each. The FXS port uses RJ45 connectors.
RemoteVu
Daughtercard
The PathBuilder S21x switch supports video over Frame Relay using the RemoteVu
daughtercard. The RemoteVu Daughtercard provides two BNC connector, video
ports accepting NTSC, PAL or SECAM video signal standards and an RJ-45, RS232/
485 camera control port used for Pan/Tilt/Zoom (PTZ) camera control.
DSU Daughtercard
The DSU daughtercard functionality suits an extended range of 56 kbps
point-to- point DDS1 interfaces that conforms to AT&T 62310 or
ANSI T1E1.4/91-006.
The DSU is FCC Part 68 registered.
Diagnostic loopbacks from the telephone company are supported; local diagnostics
are activated from the CTP.

About the PathBuilder S21x Switch 1-5
Features
Software Functionality
Introduction
Depending on the operating software AppsWare package and optional daughtercard
installed the PathBuilder S21x switch can support the following functionality and
services.
Frame Relay & X.25
Service
The PathBuilder S21x switch provides serial devices with economical Ethernet LAN
access into public or private Frame Relay WAN. Where frame relay services are not
yet available, the PathBuilder S21x switch can provide network access over X.25
services. When frame relay services becomes available, the PathBuilder S21x switch
can be easily configured and integrated to support frame relay. This fast migration
reduced network downtime and protects hardware investments.
RFC 877 and 1356
The PathBuilder S21x switch supports encapsulation of IP datagrams and other
network layer protocols over X.25 as specified in RFC 877 and RFC 1356. This
allows for interoperability with Front End Processors (FEPs) that support X.25 and
IP traffic as well as router vendors supporting RFC 877/1356.
RFC 1490
The PathBuilder S21x switch supports encapsulation of multiple protocols over
frame relay as specified by RFC 1490.
Multiprotocol
Support
Support includes SDLC, Bisync, X.25, Async, IP/IPX, PPP, MLPPP, and Routing
and Bridging, as well as many other serial protocols. Refer to the Software Release
Notice which accompanied your unit for a complete listing of protocols supported by
the PathBuilder S21x switch.

Introduction
This section describes example applications for the PathBuilder S21x switch.
LAN and Legacy
Protocol over
Frame Relay
The PathBuilder S21x switch supports multiprotocol encapsulation of IP traffic and
legacy serial protocols over frame relay as specified by RFC 1490. As shown in
Figure 1-2, a SNA cluster controller connects to a serial port on the PathBuilder S21x
switch and the Ethernet LAN connects to the 10BaseT Ethernet port. The PathBuilder
S200 series switch is fully interoperable with third party routers via RFC 1490.

Video and Legacy
Protocols over
Frame Relay -
Banking
Application
As shown in Figure 1-3, the PathBuilder S21x switch can support encapsulation of
video and legacy protocol over frame relay. This use of PathBuilder S21x switch
suits banking applications such as Automated Bank Machines (ABMs). With Dial on
Demand software feature enabled, the PathBuilder S21x switch initiates a connection
only when there is data transfer, i.e. only for the duration of a bank transaction. The
RemoteVu Daughtercard can capture video and send video streams to the central
bank’s security system.

DSU DIM and Voice
Relay Daughtercards
The PathBuilder S21x switch supports voice, video and
data traffic between the branch and central office over pri-
vate or public frame relay network. The Voice Relay
Daughtercard supports telephones, PBX, and faxes.
Connect a telephone or PABX to one FXS port on the
Voice Relay Daughtercard and all branch telephones have
access to the central office PBX. This eliminates long
distance telephone charges between the branch and
central office.
Security
Monitoring at
Branch Office
RemoteVu and DSU
Daughtercards
The PathBuilder S21x switch equipped with a RemoteVu
Daughtercard provides security surveillance and remote
monitoring of the branch office location from the central
office. The RemoteVu Daughtercard packetizes video
stream in IP and sends the data over the frame relay.
Security personnel at the central office can control the
branch office video camera from a PC running the Host
Video Workstation application.
