PCM Multiplexer (SPC10)

Overview

Centralized, single-type-specific integrated service access multiplexer adopted large-scale integrated circuits, single-chip complete the signal processing of the optical inetrface, E1 interface, the subscriber interface, mainly applied for the conversion from optical inetrface (or E1 inetrface) to the various types of data and voice interfaces.

Intigrating of PCM and PDH, or PCM and SDH, the super compatibilityof SPC10 Series solve the voice and broadband data services as well.

Used in conjunction with program-controlled machine PBX, it can achieve long-distance Telephone Number Service. They are widely applicable in integrated access of voice, data and images in telecommunications, electric power, finance, transportation, public security, army government, enterprises and other departments.

Features

*** 64kbps-rich user interfaces: FXO, FXS, EM2/4-wire audio interface, Ethernet interface, V. 35 data interface, hot line interface, magnetic interface, 2100Hz carrier magnetic card, V. 24/V. 28 data interface(RS232/RS485), and V. 24 interface with data and clock synchronous transmission, ITU 64kbps co-directional data interface(G703), baseband interrupt interface, No. 1 signaling and phone exchange cards

*** With the optical interface transmission, the line speed of Ethernet interface can reach fast, providing transparent transmission of E1 interface and user-friendly to expan

*** ADM features a powerful and flexible allotment of time slots in 2M

*** SDH/PDH/E1, small in size, compact in design, can provide a variety of audio or data transmission services. By using the switches on the front board, uplink interface can be changed freely from E1(G. 703) to PDH or SDH optical interface, no need to change devices

*** The functional card is designed in modules, and interfaces can be plugged or pulled into different combinations

Eg: Uplink E1interface: 8 channel FXO/FXS + 4 channel Ethernet/100M+1v. 35(N*64Kbps)

*** Optical interface supports 1+1 double optic interfaces protection mode(in which one is backup)compatible with single mode, no need to replace devices; Optic modules supports hot swap
