DHODT-E- PDH Fiber optic E1 G.703 sc als optical module v.35 v.24 Ethernet network communication equipment
Description
DHODT-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, 75Ω\120Ω optional), V.35 interface cards (2 V.35 ports), FXO/FXS voice channel interface cards (4-8 loop 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. DHODT-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 of various 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 (N?4K V.35, V.35, FXO/FXS, E/M, 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: DHODT-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: DHODT-E has preliminary cascade interface, which facilitates cascading (equipment stacking) to optical mutiplexer with higher E1 capacity when necessary.
