16E1 EOPDH Converter (RC6116)

Overview

RC6116 is a highly integrated device implements Ethernet frame transmission over 1～16/5 E1 links. Compliant to international standards, the device can communicate with products from other manufacturers adopting the same standards.

Features

• Capability of inverse multiplexing from one MII to 1-16/5 E1s
•  The maximum tolerated differential delay is 220ms
•  Ethernet Interface
•  Compliant with IEEE 802.3
•  100M Full-duplex mode
•  Configurable PAUSE flow control
•  Maximum frame size of 2036 bytes
•  For PHY mode, an external Ethernet switch chip is required
•  Encapsulation
•  Compliant with GFP-F Encapsulation specified in ITU-T G.7041
•  Programmable Null/ Linear header and optional FCS check for encapsulation
•  Auto-adaptive Client Data/ Client Management Frame, Null/ Linear extension header and FCS/ no FCS for decapsulation
•  Capability of LOF (Loss Of Frame) detection
•  Provide frame statistic in framer and deframer
•  Provide standard management frame
•  Virtual Concatenation
•  Compliant with VCAT and LCAS specified in ITU-T G.7042
•  VCAT & LCAS mapping into E1 complies withITU-T G.7043, G.8040
•  Differential delay detection
•  Hitless bandwidth adjustments (combined with processor)
•  Automatic removal and recovery of E1 channels when urgent alarm occur or disappear
•  Automatic removal and recovery of E1 channels when high Bit Error occur or disappear (combined with processor)
•  Support unbalanced bandwidth usage – when some E1s cannot work properly (i.e., the bandwidth of the transmitting and receiving signals can be 5 E1s and 3 E1s respectively)
• E1 Interface
•  Compliant with ITU-T G.703, G.704, G.823
•  Programmable HDB3/ NRZ code for
•  Alarm monitor and CRC error counter
•  Provide transparent channel through SA bits for the communication between local and remote microprocessor
•  Provide HDLC framer / deframer controlled by processor
•  Programmable local / tracing E1 timing mode
•  Per-port diagnostic line loopback
•  Support embedded E1 BER Tester（BERT for statistic of bit errors ）
•  Non-multiplexed Intel Processor Interface
•  Serial data input / output which is used for alarm LEDs and configuration controlled by register
•  External 4Mbits×16 (64Mbits) SDRAM 
•  QFP 208 Package, 3.3V/1.8V power supply
•  fully compatible pins for RC6116/RC6105
