ISDN Bandwidth
On-Demand
Bandwidth On-Demand provides an additional network connection for a second DTE
(router) port based on a request from the DTE. In this configuration the NP 110 ISDN
Adapter is protocol-transparent. The Router determines the protocol used.
A typical network configuration showing simultaneous Bandwidth On-Demand and
Backup connections is shown in Figure 2-5.
Figure 2-5 Typical Simultaneous Bandwidth On-Demand Configuration
The bandwidth on-demand process is described as follows:
•
User’s router detects need for bandwidth and raises DTR on its second port.
•
FrameSaver NP 110 ISDN Adapter calls predetermined number.
•
The Central Router answers the call and establishes communications with the
remote Router.
•
Communication commences between Routers.
•
User’s Router lowers DTR to terminate the ISDN connection when the
“demand” has been satisfied.

ML-PPP Support
Because the FrameSaver NP equipment is intended to operate as a demarcation device,
it cannot be dependent on co-located equipment to establish a connection. For this rea-
son, connection-associated parameters reside in the FrameSaver NP. ML-PPP opera-
tion is based on the use of CHAP or PAP ID or Caller ID to associate each incoming
call with the proper ML-PPP bundle. Because the associated router is using a single
physical port, it must be configured for PPP. The ML-PPP engine supports the Link
Configuration Protocol (LCP) required by PPP. In this case, the configuration values
are defined by the ML-PPP RFC, but are communicated to the router to ensure orderly
operation.
ML-PPP is supported on a dial-out basis on the BOD port only.
