The TCB-V.24 Tail Circuit Buffer provides bidirectional buffering at data rates up to 128Kbps in back-to-back RS-232 modem cross-connection applications such as a Tail Circuit. The 64-bit circular buffers compensate for differences between modem clock rates and limits errors to occasional data losses when the buffer overruns.

The RDS-TCB Tail-Circuit Buffer is designed to provide selectable bi-directional buffering between two data circuits that are operating at nominally the same clock rate and are capable of providing clocking as a DCE. In such cases, the timing of the two circuits is not locked to the same timing source, or may be allowed to deviate from a com-mon timing source for a length of time. The RDS-TCB meets this need by pro-viding selectable amounts of bi-directional memory from 1,024 bits up to 8,192 bits and supports synchronous clock rates up to 2.048 Mbps.

The RDS-SB is a device intended to provide a unidirectional 2.097 Mbit elastic data buffering (FIFO memory) function between two systems having nominally equivalent clocking rates. The two systems may be either running asynchronously, or may be traceable to a common timing source.

The Selectable Transmit Buffer (RSD-STB) allows DCE to DTE connections at data rates up to 10Mbps. Allows the user to even the network delays between a terrestrial and satellite network for transactions.
