ESPOD PCM Multiplexer


Categories: ,
  1. General Details

    ESPOD ES-V2030 digital cross-connect equipment integrates with PCM, Optical Transceiver, Serial to Ethernet port and other features. The equipment is widely used in the E1 network transmission, such as relay between the PBX (private branch exchange), Optical Access Network, Optical Loop Subscriber System, digital signal transmission of mobile telephone BS, it can also be used for exclusive data of optical fiber transmission, such as computer data transmission. Users include communication network of railway, airport, electricity, water conservancy, oil, bank and others.

  2. Technical Info

    Voice capacity 

    • Centralisation of PDH, perfect unity of Optical Transceiver, Ethernet fiber Converter and PCM
    • Transmission side not only can use E1, but also PDH optical interface
    • Compared with conventional PCM, main control board can integrates 2 PDH optical interfaces, which can connect remote PDH, integrate highly and save slots, maximum 26 optical direction to connect, optical port supports the single fiber and saves the transmission line for the user

    DATA Network

    • Main control board provides All of Machine Frame Ethernet Aggregation, which achives VLAN, QoS, limit of bandwidth rate and other common functions, without taking up extra slots and saving the user switches
    • Main control board provides 2048 × 2048 switching network based on 64K channel, which can achieve cross-connect between the remote device data
  3. Specifications

    Firewall & Security 

    • Multiple 1 +1 protection mechanisms:
    • Main control board 1 +1 heat copy
    • Power supply board 1 +1 heat copy
    • Channel protection between PDH dual optical port
    • Channel protection between any 2 framing E1 route


    • DV32 provides up to 30 PCM narrowband data services, can be flexibly configured many data interfaces eg. FXO / FXS / E & M / asynchronous V.24 / magnet etc. and a variety of different interfaces can be applied simultaneously, single plate can achieve common PCM multi-board function, which greatly facilitates the users to select and configure, improves integration and saves space
    • Support 2 network management including serial and Ethernet port
    • Effectively distinguish between the remote device power-down and broken fiber alarm; built-in error test and line loopback
    • Support charged pluggable board, dual power supply heat copy


    device structure

    • standard 19-inch rack-mounted with 9U height, (W × H × D) 482 mm × 399 mm × 470 mm
    • Using vertical baffle structure
    • 16 slots (including 2 power supply board slots)
