The Cisco 1750 is available in three models that
enable users to easily tailor an access solution to suit their branch office
requirements today and in the future:
- Cisco 1750—The most basic model available, this unit provides
everything a small branch office needs for data networking now, with a
simple upgrade path to support integrated voice/fax/data applications
when needed. A convenient voice upgrade kit is available to provide
voice/fax/data support as needed.
- Cisco 1750-2V Multiservice model—This model includes all the
features, memory, and DSP needed for immediate support of integrated
voice/fax/data applications with up to two analog voice ports. Voice and
WAN interface cards are available separately.
- Cisco 1750-4V Multiservice model—This model includes all the
features, memory, and DSPs needed to support integrated multiservice
voice/fax/data applications immediately with up to four analog voice
ports. Voice and WAN interface cards are available separately.
All Cisco 1750 models offer three modular slots for voice and data
interface cards, an autosensing 10/100BaseT Ethernet LAN port, a console
port, and an auxiliary port. The Cisco 1750 supports the same WAN interface
cards as the Cisco 1600, 1720, 2600, and 3600 routers, and the same analog
voice interface cards and voice-over-IP technology as the Cisco 2600 and
3600 routers, simplifying spanning support requirements. The WAN interface
cards support a wide range of services, including synchronous and
asynchronous serial, Integrated Services Digital Network Basic Rate
Interface (ISDN BRI), and serial with DSU/CSU options for primary and backup
WAN connectivity. The voice interface cards include support for Foreign
Exchange Office (FXO), Foreign Exchange Station (FXS), and Ear & Mouth
(E&M). Combined, these interfaces support a comprehensive set of
applications, including multiservice voice/fax/data integration, Frame
Relay, ISDN BRI, SMDS, X.25, broadband DSL and cable services, VPNs, and
more.
