Setting Up Basic IP Modem Services
Establishing a Network-Service Definition
Begin your implementation of basic IP UPC services by establishing a network service definition. Use
the perspectives described in Table 6-1 preceding and in the following list of design and configuration
considerations as a guide. A conservative approach is to project your current deployment and design into
a three-month, one-year, and five-year timeline.
Step 1 Project user growth and resulting line requirements (lines=users/busy-hour ratio) over the following
intervals:
3 months (example: 25 lines)
1 year (example: 50 lines)
5 years (example: 100 lines)
Step 2 Determine user-to-line ratio during busy hours.
Step 3 Determine access media to be used for dial services:
Analog lines
ISDN BRI lines
Step 4 Determine types of remote devices to support:
Analog modems
Remote LANs
PCBUS ISDN terminal adaptors
V. 1 1 0
V. 1 2 0
Step 5 Determine operating systems to support:
Windows 95
Windows 98
Windows NT
UNIX
Mac OS
Step 6 Determine if dial-in modem services will be supported.
Step 7 Rank technology priorities:
AAA design
IP design
V.90 modem performance
Step 8 Determine which access service will be used for connecting to modems:
EXEC shell sessions
PPP sessions
SLIP sessions
Step 9 Determine if multilink will be supported. If yes, indicate whether you will scale to a stacked multichassis
solution.
Step 10 Determine if PPP timeouts (accounting) will be supported.
