ZyXEL Communications 128MH The Built-In Modems, PAP and CHAP Security, DHCP Support, Call Control

Prestige 128MH PSTN Router/Hub

PAP and CHAP Security

The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol). CHAP is more secure than PAP; however, PAP is readily available on more platforms.

DHCP Support

DHCP (Dynamic Host Configuration Protocol) allows the workstations on your LAN to obtain the configuration from the Prestige at start-up.

Call Control

Your Prestige provides budget management for outgoing calls and maintains a blacklist for unreachable phone numbers in order to save you the expense of unnecessary charges.

Data Compression

Your Prestige incorporates Stac data compression to speed up data transfer. Stac is the de facto standard of data compression over PPP links.

Networking Compatibility

Your Prestige is compatible with remote access products from other manufacturers such as Ascend, Cisco, and 3Com. Furthermore, it supports Microsoft Windows 95 and Windows NT remote access capability.

1.3The Built-In Modems

The built-in modems are capable of maximum throughput of 56 Kilobits per second (kbps). Please note that due to the local telephone regulations and the line quality of your local loop, your Prestige may or may not achieve the theoretical maximum throughput.

The modems support either K56flex™ or X2™ standard, depending on the modem module installed in your Prestige. In either case, the modem is firmware upgradable to V.90, which is the latest international standard sanctioned by the ITU (International Telecommunication Union). Please visit ZyXEL’s web site at www.zyxel.com for the availability of the firmware upgrade for your model.
