centralized voice mail
You can use the Business Communications Manager auto attendant and voice mail
applications on one Business Communications Manager system within a private MCDN
network to support all the systems connected on the private network. The Business
Communications Manager can also be set up to access voice mail systems attached to
other systems, such as a Meridian 1. If the M1 is supporting the voice mail system, and the
private network is MCDN, the Business Communications Manager systems on the
network can also support the attendant call features from the M1. The Business
Communications Manager also supports centralized voice mail connected to a DSM100/
SL100, or a Succession 1000/1000M.
CHAP
Challenge-Handshake Authentication Protocol (CHAP) is a method of establishing
security on PPP links where the peers must share a plain text identifier. The caller sends a
challenge message to its receiving peer and the receiver responds with a value it calculates
based on the identifier. The first peer then matches the response with its own calculation.
If the values match, the link is established.
CHAP is a more secure procedure for connecting to a system than the Password
Authentication Procedure (PAP).
cipher
Cryptographic algorithms used as part of security authentication between the system and
servers and clients. A cipher suite contains a number of these algorithms:
• DES: Data Encryption Standard
• DSA: Digital Signature Algorithm
• KEA: Key Exchange Algorithm
• MD5: Message Digest algorithm
• RC2 and RC4: Rivest encryption ciphers
• RSA: A public-key algorithm for both encryption and authentication
• RSA key exchange: A key-exchange algorithm for SSL-based
• SHA-1: Secure Hash Algorithm
• SKIPJACK: a classified symmetric-key algorithm
• Triple-DES: DES applied three times

client
A client is a computer system or process that requests a service of another computer
system or process. For example, a workstation requesting the contents of a file from a file
server is a client of the file server.
