Light-Weight Directory Access Protocol (LDAP)

IP Office supports LDAP directory synchronization. This allows the telephone number Directory (names and

telephone numbers) held in IP Office to be synchronized with the information on an LDAP server (limited to

500 entries). Although targeted for interoperation with 'Windows 2000 Server Active Directory', the feature is

sufficiently configurable to interoperate with any server that supports LDAP version 2 or higher.

Remote Access Server (RAS)

IP Office provides RAS functionality allowing external users to dial in to the local area network from modems,

telephone adaptors and routers. Several of the previously described features and services can be applied to

the dial-in users to create a powerful Remote Access Server. Dial-in users can be authenticated using either

PAP or CHAP. Once authenticated the DHCP server can automatically assign the user an IP address to use

while connected to the LAN. Individual time profiles and firewalls can be applied to the user restricting what

they have access to and when they have access. For further security and accounting ease, IP Office can

automatically call a user back. This keeps the cost of the telephone call on the company telephone bill

removing the need to process individual expense claims.

Transaction Packet Assembler Dissembler (TPAD)

TPAD is a lightweight version of the X.25 protocol used in the retail market for transaction processing. Through

faster transaction processing a retailer can reduce the floor limit of credit authorizations and benefit from lower

transaction charges. A PDQ or credit card "swipe" telephone can utilize the digital trunks, via the DTE port or

the USB on the rear of the IP Office. Since the link between the main unit and the transaction authenticator is

digital no modems are required at either end.

Routing Information Protocol (RIP)

RIP is a distance vector protocol that allows routers to determine the shortest route to a destination network.

It does this by measuring the number of intermediary routers that need to be traversed to reach the

destination network. If more that one route exists to the same destination the shortest route is used. If a fault

occurs on the shortest route it will be remarked as being infinite and any alternative route will become the new

shortest route. This behavior can be used to add resilience into a data network. Where a customer has an

existing data network comprising of third party routers, IP Office added to the network can provide back up

using its routing and dial-up capability. RIP enabled routers share their knowledge of the network with each

other by advertising and listening to routing table changes. IP Office Supports both the RIP I and RIP II

standards.
