63 E1 STM1 SDH Multiplexer
Global Tech GT-SDH-155A 63E1 SDH is the compact STM-1 level Synchronous Digital Hierarchy (SDH) transmission system compatible with ITU-T standard. It is designed as a modular system with two 155.520Mb/s optical interfaces to provide an ultra-compact, cost-effective and high capacity platform. It provides fully cross-connect between all tributaries, and can be used as Terminal Multiplexer (TM) or an Add-Drop-Multiplexer (ADM) to build point-to-point, ring and chain transmission network.Feature# Achieve Multiplexing from 63 E1 to 2 STM-1 optical interfaces # 1U height, 19 Inch width standard # Service interface* Two STM-1 optical interfaces, SFP optical module (LC connector)* Maximum 63 E1 interfaces compliant with ITU-T G.703, optional unbalanced/ balanced interface# System interface* Ethernet management interface: EMU (RJ45 connector) * RS232 network management interface: CONSOLE (RJ45 connector)* RS232 user channel interface: RS232 (RJ45 connector)* External synchronization interface / Extendable management interface : ETS1/EXM1, ETS2/EXM2 (RJ45 connector)* Engineering Order Wire (EOW) interface: PHONE (RJ11 connector) * UALM and DALM output interface: U/DALMO (DB9 connector)# Timing mode* STM-1 line timing (T11,T12)* Tributary timing from E1-1 to E1-63 (T2)* External timing source input (T31/T32), 2048Kbit/s by default and 2048KHz selectable* External timing output (T41/T42), 2048Kbit/s by default and 2048KHz selectable* ITU-T G.813 internal oscillator* The timing source can be auto-switched according to SSM or operator settings# Supports 1+1 protection and Automatic Protect Switch (APS) with the switching time less than 50ms # Supports Remote power Down Detection (RPD) and Auto Laser Shutdown (ALS) # Supports embedded BERT and various loop back for troubleshooting# Highly efficient management system* Supports NE management based on CLI command via RS232 interface or TELNET* Supports Network management based on PC via unified platform: GTVIEW* Supports three network management types: Traditional DCC management, Inner DCN management (by some VC12 channel) and outer DCN management (by E1 cable via outer EXM interface). # Power system* Two backup power supply* 220V AC or-48V DC single power* -48V DC & 220V AC double power * -48V DC & -48V DC double power * 220V AC & 220V AC double power * Power consumption less than 25WTechnical Parameter System Fabric* Cross Connect: 4* 4 VC-4 Optical Interface* Optical Port: S1.1, L1.1, L1.2* Connector: SC, FC* Wavelength: 1310nm, 1550nm* Coding: NRZ* Max.
