The terminal adapters in this topic have been evaluated. They are
suggested only for the origination of ISDN remote connections from the iSeries™ server.
3Com Impact IQ ISDN:
This terminal adapter is not
suggested for iSeries server
for the following reasons:
- The terminal adapter does not support V.34 analog modem connections. However,
it may support V.34 analog modem connections by using the external RJ-11 connection.
- The terminal adapter does not currently support V.90 connections.
- The terminal adapter may not connect to iSeries server at speeds greater than
115 200 bps.
- The terminal adapter does not automatically support Challenge Handshake
Authentication Protocol (CHAP). However, setting S84=0 allows the iSeries server
CHAP authentication to be performed.
- The iSeries server
is unable to determine when the connection ends when monitoring the Data Set
Ready signal from the terminal adapter. This results in a potential system
security exposure.
Motorola BitSurfr Pro ISDN:
This terminal adapter
is not suggested for iSeries server for the following reasons:
- The terminal adapter does not support V.34 analog modem connections. However,
it may support V.34 analog modem connections by using the external RJ-11 connection.
- The terminal adapter does not currently support V.90 connections.
- The terminal adapter may not connect to iSeries server at speeds greater than
115 200 bps.
- The terminal adapter does not automatically support CHAP authentication.
However, setting @M2=C allows iSeries server CHAP authentication to
be performed.
- The terminal adapter does not automatically permit answering both single-link
and Multilink PPP calls. The remote origination terminal adapter must be set
to the same protocol (single-link or Multilink) as the answering terminal
adapter.
- The iSeries server
hardware flow control mechanism does not work well with this terminal adapter.
This results in degraded performance when the iSeries server is sending data on a Multilink
PPP connection.
