Transport SR Series Installation Guide
1 Introduction
The Transport SR and other models described in this guide are compact IP routers that
facilitate the transmission of data over UMTS, HSDPA, EVDO, GPRS, EDGE and/or
PSTN networks. All models incorporate a 4-port 10/100 Ethernet switch. Depending on
the model, each unit also incorporates one or more WAN interfaces as follows:
SR44-E, H, U – wireless GPRS/EDGE/UMTS/HSDPA/HSUPA only
SR44-C
The routers can be configured either by using commands entered at the serial port (much
like a modem), or via the built-in Web interface. We recommend that you use the Web
interface whenever possible.
In addition to many standard LAN and Internet protocols such as PPP, Transport SR
series products provide a combination of powerful but easy to use configuration,
management and diagnostic tools. This makes them simple and cost-effective solutions
for migrating existing terminal or telemetry equipment, which use wired networks (PSTN,
ISDN, etc.), to wireless operation.
