DHODT-SDH,a new-style optical transmission multi-service access
device(hereafter as New-style Access Device for short),is a
single-layer SDH product of the latest generation.Taking SDH
technology as the core,DHODT-SDH provides convergent
access,collection,switch,transmission and management functions for
TDM service and broadband IP service.It is an optical transmission
platform of integrated access that applicable for traditional
telecom services and broadband data services.In addition,it is
compatible with all PDH services,which makes it applicable for
multi-service integrated access for edge networks,various special
networks and big telecom customers etc. The innovative architecture
of DHODT-SDH device has expanded SDH technology to edge
network.Therefore it is a high-end PDH access device that has taken
the advantages of SDH technology into account,which can be applied
to meet the current developing demands of big capability and access
device integration for various edge devices of access network and
special nerwork etc. Features >>Generally speaking,DHODT-SDH
new-style multi-service optical transmission platform possesses the
following features; >>Provides standard STM-1 optical
interface,supports ALS(Automatic Laser Shutdowm)function and abides
by G.664 standard; >>Provides two optical interfaces#1-01 and
#1-02,four service access interfaces #2,#3,#4 and #5,and supports
hot swap; >>Provides 4xE1,10/100Base-T(VC-12 or VC-3
bandwidth)and 2xV.35 interfaces so as to intermix daughter boards
of various services and allow different services accesses;
>>Provide order-wire telephone interface( two-line style) to
full point to point calls; >>Provides two relay-style
overhead alarm output interfaces for prompt alarm and deferred
alarm,and two switch input interfaces; >>Provides random
add/drop of VC-12 channel ,with the service interval to be randomly
scheduled; >>E1 signal has the functions of retime and
pointer justification bypass; >>Supports Ethernet interfaces
sharing and point-to-point application and be compatible with all
PDH services; >>With excellent synchronization feature which
allows to be synchronized with the line clock or the highly precise
internal pulsating source.The line clocks of two optical directions
can also be input as the clock reference input. >>Diverse
topology:supports various nerworking modes such as
point-to-point,chain,ring(Center utility (CU)also supports T
shape,cross ring and tangent ring)etc; >>Supports various
device control modes such as internal loop-back,external
loop-back,enable and disable etc; >>Provides standard SNMP
uniform network management system; >>To be managed
conveniently; supports inquiry and conflguration of every node and
every board in the network through operating panels without help of
nerwork management; >>Comprehensive and flexible modes of
inquiry and configuration:a.panel;b.RS232 hyper terminal(standard
TL1 command line);c.RS485 network management software;d.SNMP agent
module,displaying through the interface of PC network management
software; >>Power supply adopts +1 hot standby,taking
DC-48V/AC220V/DC-48V+AC220V(dual supply)as options;with an alarm
function of remote terminal break-off. Our major products series
