2. 8/16 x E1/T1 over Ethernet Multiplexer (TDMoIP) Slide 2 Product Overview  VCL-8/16xE1/T1 over Ethernet (TDMoIP) provides the user with E1/T1 over Ethernet (IP) conversion and allows the user to transport upto 16 E1/T1 channels (carrying data or voice) over Ethernet (IP) Network  Support SNMP V2 monitoring and traps  VCL-8/16 x E1/T1 over Ethernet multiplexer (TDMoIP) product supports upto 8 or 16 E1s/T1s (user selectable) and 5 Gigabit electrical ports and 1 Giga Byte (GE) optical port  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 1 and 2 port TDMoIP versions  The uplink ports and user data ports are IEEE 802.3 compliant, 10/ 100/ 1000M auto-negotiating Ethernet ports.

3. 8/16 x E1/T1 over Ethernet Multiplexer (TDMoIP) Slide 3 Product Overview  The QoS features include short and stable transmission delay, low jitter and wander, etc.  Support 802.1Q based VLAN tagging and 802.1p QoS function  VLAN settings for E1 services with 802.1Q and QinQ mode  Supports 120 Ohms balanced and 75 Ohms unbalanced (optional) E1 ports  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  Support 1+1 AC and / or DC redundant power supply options  Compact and low cost.

4. 8/16 x E1/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.

5. 8/16 x E1/T1 over Ethernet Multiplexer (TDMoIP) Slide 5  Up to 16 E1/T1 Ports supported  Provides 5 Giga Byte (GE) electrical ports and 1 Giga Byte (GE) optical port. All 6 Giga Byte (GE) ports serve as network uplinks or users ports and any of the 5 Giga Byte (GE) electrical ports may act as Management Port  E1/T1 signal is a TDM signal which transmits information in a constant bit rate of E1@ 2048Kbps, T1@ 1544Kbps  User-friendly Web server supported for easy setup and maintenance  Supports SNMP V1/V2 network management  Ethernet built-in layer 2 switch, supports VLAN, complies with IEEE 802.3x, 802.1P  Provide two removable E1 cards (add/remove), each card supports 8 E1/T1s  Point to point and point to multipoint application supported. Features and Highlights

6. 8/16 x E1/T1 over Ethernet Multiplexer (TDMoIP) Slide 6  PCM frame synchronization protection  User definable encapsulation packet size for different applications  Support Ethernet encapsulation and UDP/IP protocol encapsulation  Support VLAN settings for E1 service and in-band VLAN management  Jitter buffer for packet delay variation (PDV)  Local Ethernet port throughput limit assuring E1 QoS  120Ω balanced E1/T1 port, RJ-45 connector  Supports 75Ω unbalanced port (optional)  Stable E1 clock recovery, low jitter and wander  Low processing delay for E1 channels, high bandwidth usage efficiency  Local and remote E1/T1 LOS and AIS and packet loss indication for trouble- shooting and maintenance. Features and Highlights

7. 8/16 x E1/T1 over Ethernet Multiplexer (TDMoIP) Slide 7  Supports 1+1 redundant power supply which can be configure various combinations (AC, DC, AC+AC, AC+DC and DC+DC)  AC power supply range 110V ~ 240V AC  DC power supply range 36V ~ 72V DC. Features and Highlights

8. 8/16 x E1/T1 over Ethernet Multiplexer (TDMoIP) Slide 8  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 1 and 2 port TDMoIP version Establishing point to multipoint E1 / T1 link over wireless bridges (Ethernet Radios) 1 and 2 port TDMoIP version.
