Justification:
The WAN consists of Cisco Systems, Inc. equipment that is centrally
managed through Cisco Works 2000, HP Openview, 3DV and 3COM Transcend.
A single vendor LAN/WAN approach ensures compatibility and increases the
level of service available to customers. A single analog modem standard
is necessary to support the diverse remote and mobile computing needs
of All University departments. V.90 technology improves speed and performance
by allowing modems to receive data at up to 56 Kbps over the standard
public-switched telephone network (PSTN).
Technical
Considerations:
All devices should be SNMP manageable. (Does everyone know what SNMP
means?) As of February 1998, the 56Kb V.90 became the official ITU adopted
standard for high-speed analog modems, providing the interoperable features
necessary for two competing proprietary standards -- K56flex and X2, to
communicate. V.90 now is the universally compatible solution. Modem manufacturers
ship upgrades to maintain that their 56K and V.90 modems are capable of
being updated to enhance compatibility and performance. This requires
flash memory and RAM DSP chips.
