TN726B
The TN726B has 8 serial asynchronous EIA ports with modem interfaces connected through asynchronous data units (ADUs) to EIA ports (such as RS-232) on DTE. The TN726B uses Mode 2 or Mode 3 data transfer protocol. The DTE can be adjuncts and peripheral equipment such as data terminals, printers, host computers, personal computers (PCs), graphics and facsimile systems, and call detail acquisition and processing systems (CDAPSs).
With software-administered system access ports, a TN726B connects through an MDF to a TN553 packet data line circuit pack. The TN553 then converts mode 2 protocol to mode 3 protocol transferring the TN726B from the packet bus to the TDM bus for EIA connections.
Each port on a TN726B has TXT (terminal, transmit, and tip), TXR (terminal, transmit, and ring), PXT (port, transmit, and tip), and PXR (port, transmit, and ring) signal leads.
