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,
75¦¸120¦¸ 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 481216E1 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.
