7855 Modem - Compatibility with Bell 208 A/B Modem

Applicable to: EMEA


Description:
Can the IBM 7855 modem work with a Bell 208 A/B modem?

Solution:
No, the Bell 208 modulation scheme is a 4800 bps half-duplex scheme and the 7855 complies with CCITT V.32 which is a 4800 or 9600 bps full duplex modulation scheme. No V.32 modem can operate with a Bell 208 modem because the modulation schemes are incompatible.
