1xE1/T1 over Ethernet Multiplexer (TDMoIP) Slide 1Updated: April 2010Orion Telecom Networks Inc xE1/T1 over Ethernet Multiplexer (TDMoIP) Product Presentation

1xE1/T1 over Ethernet Multiplexer (TDMoIP) Slide 2 Product Overview  VCL-1xE1/T1 over Ethernet (TDMoIP) provides the user with E1/T1 over Ethernet (IP) conversion and allows the user to transport E1/T1 channels (carrying data or voice) over Ethernet (IP) Network  Very Compact and low cost  It is an E1/T1 extension device which utilizes the Ethernet / IP Network to transport E1 or a T1 signal in real-time  Useful for the Real-time applications carrying VOICE, VIDEO and DATA  Compatible with 2 port, 8 port and 16 port TDMoIP versions  The equipment can be installed and used in a point-to-point topology  Multiple equipment can be used in different (Remote) sites in point to multipoint topology by using 2, 8 and 16 port TDMoIP equipment in central sites.

1xE1/T1 over Ethernet Multiplexer (TDMoIP) Slide 3 Product Overview  The QoS features include short and stable transmission delay, low jitter and wander etc.  Suitable good for achieving higher bandwidth utilization  It converts the E1/T1 frame format into Ethernet Data for transmission over the Ethernet or IP Network and then re-converts the Ethernet data back into E1/T1 frame format at the far-end terminal, to inter-connect two or more E1/T1 devices over the Ethernet / IP Network  Optional 220V AC (110~240V AC) and -48V DC (18~72V DC) input power supply.

1xE1/T1 over Ethernet Multiplexer (TDMoIP) Slide 4 How it works  The equipment is a TDM / Packet processing unit.  It converts E1/T1 data stream into Ethernet packets with or without IP headers.  These packets are transported over the Ethernet network.  At the far-end the packets from the uplink Ethernet port are sorted and processed to re-assemble into the original E1 or T1 data stream.  It also uses algorithms to recover the E1 or T1 clock synchronization and to ensure that the reconstructed clock will meet the stringent requirement of TDM applications.

1xE1/T1 over Ethernet Multiplexer (TDMoIP) Slide 5  Supports user selectable one E1 or T1 port  Easy to use and configure by any web browser  E1/T1 signal is a TDM signal which transmits information in a constant bit rate of 2048Kbps, 1544Kbps.  Support point-to-point link establishment over IP Network  Support point-to-multipoint link establishment over IP Network with 2, 8 and 16 port TDMoIP equipments  Stable E1/T1 clock recovery, low jitter and wander  Low processing delay for E1/T1 channel, high bandwidth usage efficiency  Resistance to packet loss, with PCM frame synchronization protection  Adequate jitter buffer to resist packet delay variation  Auto parallel or cross cable adaptive Ethernet ports. Allow easy connection to other Ethernet equipment. Features and Highlights

1xE1/T1 over Ethernet Multiplexer (TDMoIP) Slide 6  Local and remote E1/T1 LOS and AIS and packet loss indication for trouble- shooting and maintenance  Support 1+1 backup uplink ports  Supports Automatic Ethernet negotiation function and configurable 10M/100M, Half / Full duplex working modes  Optional powers 220V AC and -48V DC. May be ordered with either power option  Idle for connecting offshore sites with central site over Ethernet / IP network in very low investment  Supports transparently passing the VLAN tagged Ethernet DATA  Works fine with other TDMoIP equipment having multiple E1/T1 ports  Robust and cost effective. Features and Highlights

1xE1/T1 over Ethernet Multiplexer (TDMoIP) Slide 7  The equipment may be used for the following purposes: Connecting point to point E1/T1 devices over Ethernet or IP network Establishing point to point E1/T1 link over wireless bridges (Ethernet Radios) Connecting point to multipoint E1/T1 devices over Ethernet or IP network with 2, 8 and 16 port TDMoIP version Establishing point to multipoint E1/T1 link over wireless bridges (Ethernet Radios) with 2, 8 and 16 port TDMoIP version.
