Omni 56K Plus Series User’s Guide 2.5.6 Data Compression In the modem, the data compression is activated in an attempt to reduce the number of bits actually sent. The receiving modem applies these techniques in reverse to recover the actual data from the compressed data stream. Omni 56K Plus modems support V.44, V.42bis and MNP5 data compression protocols. Data compression needs an error-free data link to work correctly, otherwise the corrupted compressed data stream will ruin the decompression process.

PAGE 20
Omni 56K Plus Series User’s Guide Setting S48.0=1 will cause the modem to report CND information in its ASCII coded hexadecimal raw data format. The DTE software is responsible for explaining the data. Please refer to the Bellcore Technical Advisory document TRNWT-000030 for the exact data format. The above Caller ID scheme applies to the North America area. Different countries may employ different Caller ID schemes, check if the scheme used in your country is supported before using the Caller ID feature.

Omni 56K Plus Series User’s Guide security is used when the remote modem is also a ZyXEL modem; type 2 security is used when the remote modem is any other brand of modem. With the type 1 connection, the dial-in (remote) modem will send in its supervisor password for checking at the initial connection handshake, and the local modem will check this password against its pre-stored acceptable password list.
PAGE 22
Omni 56K Plus Series User’s Guide Before the security type or level can be changed, the modem requires the supervisor password. For type2 security, the remote site will be prompted to enter the user password. A maximum of 3 tries in 40 seconds is allowed. If a correct password is not entered within this time limit, the line will be disconnected. If the remote site is to enter the call-back number, it will be prompted to do so. 2.6 Fax function 2.6.
