your requirements. Examples of WANs are Internet access providers (IAP),
Internet service providers (ISP), and corporate networks.
Potential applications
Potential applications of the 1-Meg Modem Service include the following:
• work-at-home
The subscriber uses the 1-Meg Modem Service, including the transport
network, to connect to their corporate network.
• Internet access
The subscriber uses the 1-Meg Modem Service, including the transport
network, to connect to their ISP.
• small office communications
The subscriber uses the 1-Meg Modem Service, including the transport
network, to connect to their corporate network. Two small offices can
communicate through the 1-Meg Modem Service and depend on the
transport network for interconnection.
Compatibility
This section describes compatibility between the 1-Meg Modem Service and
other services.
Voice services The 1-Meg Modem Service shares many components with the
existing voice service. Some of these components are the following:
• Star Hub hardware, including power supplies and distribution
• the subscriber's copper loop
Other data services The 1-Meg Modem Service can function with the
following data services in the same binder group:
• integrated services digital network (ISDN) basic rate interface (BRI)
• asymmetric digital subscriber line (ADSL)
• high bit rate digital subscriber line (HDSL) services
The 1-Meg Modem Service can function with T1 services in adjacent binder
groups.
Ethernet The Ethernet interfaces at the 1-Meg Modem and the DBIC meet
standard ANSI/IEEE Standard 802.3 with one exception. The 1-Meg Modem
does not support the truncated binary exponential backoff algorithm described
in section 4.2.3.2.5 of the IEEE802.3 specification. This exception allows the
best use of the bandwidth on the link. This exception also confirms a standard
allocation between multiple users.
