Fiber Optic equipment PDH fom E1 g.703 v.35 fxo fxs module:DHODT-E
cenny[at]veecom.com.cn Description Integrated FOM series Introduce
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,
75ohm120ohm optional), V.35 interface cards (2 V.35 ports or 4 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 481216E1
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, 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. Technical Specification ELECTRICAL Interface code
