Time Profiles
Time profiles set the operational times for service. For example, a time profile could be set up to make
Internet Access available to staff only during lunch times. Using time profiles it is also possible to define an
alternative service to operate outside the operational hours of the main service. This may be used to take
advantage of alternative tariffs at off peak periods. Switching to this fallback service can also be controlled
manually by dialing a secure short code from a handset. This can be particularly useful in allowing quick
restoration of service in the event of an ISP failure. This feature also applies to days of the week or specific
calendar dates.

Password Authentication Protocol (PAP)
PAP is a method of authenticating the remote end of a connection using unencrypted passwords.
Challenge Handshake Authentication Protocol (CHAP)
Challenge Handshake Authentication Protocol allows an incoming data call to be authenticated using encrypted
passwords. The system also provides the option to periodically reaffirm the authenticity of the caller during the
data call.

Data Header Compression
IP Header Compression (IPHC) reduces the header size of the data packet to gain bandwidth efficiency over
Wide Area Networks, but adds to transmission latency.

Data Compression
IP Office supports both Microsoft Point to Point Compression and Stac Lemple Ziv to provide greater
throughput on slow speed wide area network links.

Bandwidth Allocation Control Protocol (BACP)
Bandwidth Allocation Control Protocol allows the negotiation with the remote end of the data call to request
additional calls to be made to improve aggregate data throughput.

Callback
Three types of call back are supported
·
LCP (Link Control Protocol)
After authentication the incoming call is dropped and an outgoing call is made to a predefined number
to re-establish the link.

Callback CP (Microsoft's Callback Control Protocol)
After authentication from both ends, the incoming call is dropped and an outgoing call to a predefined
number made to re-establish the link.

Extended CBCP (Extended Callback Control Protocol)
Similar to Callback CP however, the Microsoft application at the remote end will prompt for a
telephone number. An outgoing call will then be made to that number to re-establish the link.

Domain Name Service (DNS) Proxy
Domain Name Service servers provide the translation of names such as www.avaya.com to the domain’s IP
address required to establish a connection. IP Office provides this service to PCs on the network by proxy.
