Configuring WAN Access
A MAX unit supports up to four T1- or E1-line connections. It also has a serial WAN port,
which typically connects to a Frame Relay switch, and six slots for expansion cards. Expansion
cards can provide other types of WAN connections. Digital-modem cards and V.110-modem
cards provide communications with analog modem users and V.110 Terminal Adapter users,
respectively. In Japan, MAX units support Personal Handyphone System (PHS). You can
install and configure an ISDN BRI card if your connections do not warrant the expense of a T1
or E1 line. With the Host/BRI module, the unit emulates a telco switch providing ISDN BRI
lines to local hosts. The BRI/LT card supports Lucent’s ISDN Digital Subscriber Line (IDSL)
standard for voice and data transmissions. To provide the bandwidth needed for video
teleconferencing, Host/AIM6 and Host/Dual cards support two types of inverse multiplexing:
Bandwidth ON Demand Interoperability Group (BONDING) and Ascend Inverse
Multiplexing (AIM). If your unit connects only to ISDN lines and supports only
digital-modem cards, call routing is preconfigured. You must configure it, however, if you
have a mixture of cards or if the WAN lines do not support ISDN signaling.
