Ppp Multilink - ZyXEL Communications P-202H V2 User Manual

Extensive Analog Phone Support
The ZyXEL Device is equipped with two standard phone jacks for you to connect analog
devices such as telephones and FAX machines. It also supports supplementary services such
as call waiting and 3-way calling.
Incoming Call Support
In addition to making outgoing calls, you can configure the ZyXEL Device to act as a remote
access server for telecommuting employees.
Outgoing Data Call Bumping Support
Call bumping is a feature that allows the ZyXEL Device to manage an MP (Multilink
Protocol) bundle dynamically, dropping or reconnecting a channel in a bundle when
necessary. Previously, the router did this for voice calls only, but now with this new feature,
the ZyXEL Device can drop a channel in an MP bundle if there is a data packet to another
remote node.
CLID Callback Support For Dial-In Users
CLID (Calling Line IDentification) is an authentication method to identify a dial-in user.
CLID callback is used as an ISDN toll saving feature because a call can be disconnected
immediately without picking up the phone.
TCP/IP and PPP Support
• TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.
• PPP/MP (Point-to-Point Protocol/Multilink Protocol) link layer protocol.
Dial-on-Demand
The Dial-on-Demand feature allows the ZyXEL Device to automatically place a call to a
remote gateway based on the triggering packet's destination without user intervention.

PPP Multilink

The ZyXEL Device can bundle multiple links in a single connection using PPP Multilink
Protocol (MP). The number of links can be either statically configured or dynamically
managed based on traffic demand.
Bandwidth-On-Demand
The ZyXEL Device dynamically allocates bandwidth by dialing and dropping connections
according to traffic demand.
