1-4E1 to 30 / 60 channel FX (O / s) telephone (optional magnet / E & M / 4-wire audio) + Nx2M network port
Tw-pcm2020 series integrated access equipment is an integrated access equipment designed by international advanced integrated circuits, programmable logic circuits and high-speed microprocessors. It integrates PCM multiplexing, slot crossover and other technologies, and uses the crossover technology to realize the dynamic allocation of slot resources, so as to improve the utilization of line resources.
The transmission medium is 4E1 channel with multiple service configurations. The service disks and cards with various functions can be configured arbitrarily according to the user's needs. Business options are very flexible.
The network port with standard capacity of 1-30 line telephone and one channel of nx2m bandwidth can also be used as a set of network bridge providing multi-channel telephone interface. The time slot occupied by the telephone can be allocated to the network port of NxE1, which greatly improves the utilization efficiency of bandwidth.
◇ voice function; 30 ~ 60 telephone channels
◇ Other service interfaces are configured as FXO / FXS / magnet / E & M / 4-wire audio / Ethernet / RS232 / 422 / 485, etc. according to user requirements
◇ ~ 2 physically isolated Ethernet interfaces, and the bandwidth is configured according to user requirements (dynamic / static)
◇Modular power supply design; AC220V, dc-48v dual power supply mode
◇ Perfect network management function to detect various states of the equipment in real time
◇ 19 inch 1U aluminum profile chassis
