bisync

(BInary SYNChronous) A major category of synchronous communications protocols used in mainframe networks. Bisync communications require that both sending and receiving devices are synchronized before transmission of data is started. In the IBM world, bisync was superseded by SDLC. Contrast with asynchronous transmission. See SDLC.

Using Blackboard Vista[TM], combined with bisynchronous and other collaborative technology, the course had students from UMass Boston and from the University of Pannonia in Veszprem, Hungary working collaboratively in an online course.

Through more than 15 years and 100,000 installations, Cleo has set worldwide performance standards for SNA, bisynchronous, asynchronous and Internet connectivity tools.
The services are based on AT&T-installed FRADs, which assemble packets from legacy SNA and bisynchronous traffic into data frames tailored for frame relay transport.
An advantage of EDI over EFS is that, in the past, EFS usage required the tax return transmitter to purchase a bisynchronous modem costing about $2,000, which is different than the standard asynchronous modem that is purchased with most PCs (the IRS is planning to allow standard asynchronous modem usage for EFS during the 1995 tax season).
However, they must buy both special communications software (costing between $500 and $1,500) to translate data into a language compatible with IRS computers and a special 4800-baud bisynchronous modem (which costs between $800 and $2,200).
The package includes TaxLink software and SyncLink modem card, which is compatible with Bell 208B for dial-up bisynchronous communications with IRS at 4800 bps using the IRS 3780 protocol.
