T-336Cx dedicated line MODEM

The T-336 series MODEM is a high-performance, synchronous/asynchronous, full duplex/half duplex, multi standard MODEM that can operate on two-wire dial-up lines and two-wire/four wire dedicated circuits. The T-336 series not only provides security checks for dial-up internet access, but also offers security checks for automatic fallback and leased lines. The TRS16 rack can accommodate up to 16 data machine cards, including 16 ports, control units, and single or dual redundant power supply units. If one power source fails, the other power source can provide power to the entire rack.
⊙ T-336Cx desktop style
⊙ T-336Nx single channel card, can be used for Taiwan Union TRS-16 chassis
⊙ T-336NDx dual channel card, can be used for Taiwan Union TRS-32 chassis
