| | Product Introduction PCM-16 / 30 is a miniaturization agile multifunction access equipment. Possess manifold tone and ports to fulfill various need of user. This device has four standard E1 ports and can connect to other transmission apparatus. Supports the cross connection of inner time slot function, come true the agile configuration of time slot between four E1 ports and date ports. Supports DI and ADM functions. Product Feature 1 Supports various services for users, such as traditional phone, 64Kbit / s synclastic date terminal, asynchronous date terminal, public telephone, hot line 2 / 4 line audio frequency, EM signal, E1 interface and so on 2 Each device supports 16 / 30 channels audio frequency ports or low rate date port. Inner installation 16 / 30 channels E and M signal channel, possess four channels high speed V35 date rate ( N* 64K) and one 10BASE- T date port, impropriate time slot can be set. 3 Supports cross connection function, user interface can discretional assign time slot between four E1 channels, Also time slot can cross discretionally between four E1 channels. 4 Types of user service equipped with agility and convenience, auto-negotiation various types of user service interface and can be mixed equip ( include LAN tone channel and 5 Supports remote end device telemonitoring function 6 Convenience to maintenance, small in size and save space 7 Monitoring system can be equipped to inspect and manage the operation of network as requested Technologies reference 8 E1 interface: Line code: HDB3 Bit rate: 2048KBIT / S + -50ppm Frame structure: ITU-G. 704, ITU-G. 706 Impedance: 75ohm ( unbalance) or 120ohm ( balance) optional Connector: BNC 9 V. 35 interface: Port rate: Nx64K ( N= 1~ 32) Port type: DB25 with six V. 35 ( equip fully) 10 10Base-T interface: Port rate: 10Mbit / s Standard: IEEE802. 3 Port type: RJ11 with two ports ( equip fully) 11 RS232 interface: Working manner: | | |
