2. Product Features
- 19-inch 3U standard rack, with 2 power supply card slots, 2 main control card slots, and 11 service card slots;
- Dual 48V power supply, supporting 1+1 redundancy protection;
- Dual main control, supporting 1+1 redundancy protection;
- Main control card: Supports a full cross-connect capacity of 7200×7200 64K timeslots, provides user interface access and management, data and signaling cross-connection, system synchronization, and equipment networking control and management; supports digital level adjustment for all E1 channels within a single-end device. The main control board supports remote online upgrade function;
- E1 service card: A single card provides 24 E1 interfaces, wired through European-style connectors, and supports remote online upgrade function;
- NMS card: Supports online collection of TS16 signaling formats from third-party manufacturers via network management software and automatic saving. Signaling format settings can be applied to any 64K timeslot among the 240 E1 interfaces, enabling interoperability of telephone services with PCM equipment from any manufacturer;
- Test card: Equipped with a test port configured as an FXS interface. Through network management, the test port can be used to perform tests such as sending ringing current, sending audio, receiving audio, three-way calling, two-way calling, monitoring, and bidirectional loopback of 64K timeslots for specified timeslots.
- The device also supports insertion of 64K and N*64K service cards. The type and quantity of services can be arbitrarily configured within the chassis, with up to 16 channels of 64K services per slot, supporting FXS/FXO, magneto, 2/4-wire E&M, RS232/RS422/RS485, GSM/CDMA services.
