ISDN Account Rates

64K ISDN service is available at $90/month ($270/quarter), or you can combine two channels for 128K service at $170/month ($510/quarter). We suggest that you start at the lower rate, when you outgrow the lower bandwidth, switching up to the higher is a phone call away.

Configurations and Settings

ISDN access is via a dedicated ISDN router supporting CHAP and PAP authentication. Your ISDN equipment should support synchronous or V.120 PPP at 64Kbps, or 128Kbps with MultiLink PPP. Compression (STAC&tm;) should be available by 4Q97, at no extra charge.

We have tested the following configurations:

Our lead time on establishing new account service is 24 hours.

The lead time for Ameritech installation of new ISDN lines is 2-6 weeks.
Ameritech charges a per-minute rate for business ISDN calls and for residential calls beyond the 8-mile 'A zone' limit. Call Ameritech for details.

Ameritech's new tariff appears to require an additional $6 monthly fee in order to have residential ISDN service with untimed A-zone calls. For more information about Ameritech rates and services call 1-800-TEAM-DATA (800-832-6328).

Please Note
Most personal computers cannot utilize the full bandwidth of a 128K (2-channel) ISDN connection through a standard serial card and ISDN 'terminal' device. We recommend an ISDN Router for 128K service.
