Description

Integrated PDH FOM series, E1 v.35 fxo fxs RS232 RS422 RS485 module

Introduce

PDH-E is born with a capacity of transmission interfaces of 16E1 that can be expand to 32E1+ 40M. The equipment also provide various interface modules, such as E1 interface cards ( 4 G.703 ports, 75ohm/ 120ohm optional) , V.35 interface cards ( 2 V.35 ports or 4 V.35 ports) , FXO/ FXS voice channel interface cards ( 4-8loop interfaces) , E/ M interface cards ( 4-8 2/ 4-wire audio interfaces) , data interface cards ( 4-8 RS232 or RS485 data channels. They are used to transmit asynchronous data. Self-adaptation of speed can be up to 115.2K) , etc. PDH-E is a suitable choice to provide voice, data and video services for cities and industrial districts. Its optional interfaces support overall business transmission of large customers and customer groups such as medium-and-small-scale enterprises, governmental organizations, schools and intellectualized villages. Open standard interfaces are employed to guarantee prompt interlinking ofvarious equipments.

Features

Optical path backup: With the option of 1+ 1 Optical Redundancy ( Protection Switching) , in which the transmission automatically switches to a STANDBY optical link in the event of a failure of the PRIMARY optical link. E3 or E6 switch or mandatory switch of optical path can be configured to meet requirements of network of high reliability;

Network management: Furnished with network management interface ( RS485) that facilitates the realization of uniform network management;

Easy to configure: Combination of main system board and various function modules can produce 4 8 12 16E1 optical multiplexers and multiple optional traffic interfaces to meet requirements and customized demands of different users;

Various function modules: User interface modules ( Nx64K V.35, V.35, FXO/ FXS, RS232/ RS485, etc.) ; Service telephone module, network management module ( RS422/ 485, RS232, 10BaseT interfaces, etc.) , RS232 data channel module, warning leading-out terminal module, switching value channel module, etc.

Complete functions of alarm indication: PDH-E is capable of monitoring alarm status of local and remote equipments;

Various functions of loop-back test: Each E1 channel can complete local and remote loop-back independently;

Transmission distance of 30 kilometers without relay ( 80-kilometer remote transmission equipment is prepared for your selection) ;

Modular and compact design of the complete appliance ( 19" 1U structure is used) ;

Convenient to extend capacity: PDH-E has preliminary cascade interface, which facilitates cascading

( equipment stacking) to optical mutiplexer with higher E1 capacity when necessary.
