1. Slide 1 Orion Telecom Networks Inc. - 2010Slide 1 xcvcxv Updated: April, 2010Orion Telecom Networks Inc. - 2010 SafeComm 16 T1 Links (48 T1 Ports) (1+1 Automatic Protection Switch) Product Presentation

2. Slide 2 Orion Telecom Networks Inc. - 2010Slide 2 SafeComm 16 T1 Links (48 T1 Ports)  Used to protect upto 16 point-to-point T1 links and to provide an alternate communication route for each T1 Link between any two points in a T1 network.  In the event of the failure of the primary (main) T1 communication route, the SafeComm, 16 T1 Links 1+1 APS equipment, automatically switches the T1 traffic to a secondary (standby) T1 route  Data transported on the T1 Links is transparent and protocol independent  SNMP V2 Traps for alarm reporting  Available in a 2U high, 19-Inch rack mount chassis. Product Overview

3. Slide 3 Orion Telecom Networks Inc. - 2010Slide 3  Allows the user to design 1+1 (protected) redundant T1 routes on similar (fiber-fiber), or complementing (fiber-radio) transmission mediums  Transport A-bis Interface on redundant T1 links  Provide 1+1 Protection / Alternate Routing Path between BSC and BTS  Used to design 1+1 redundant (protected) T1 rings on PDH networks, which otherwise would not be possible with PDH technology  The criterion for switching between the primary (main) and the secondary (protected/standby) routes is user programmable is Loss-Of- Signal on T1 links, or AIS (All-Ones AIS alarm) condition  May be used in a point-to-multipoint configuration to provide 1+1 Protected / Alternate Routing Path between one location and multiple locations (as shown in application diagram). Applications : SafeComm 16 T1 Links (48 T1 Ports)

4. Slide 4 Orion Telecom Networks Inc. - 2010Slide 4  High density protection switching equipment (upto 16 T1 Links i.e. 48 T1 Ports)  Ensures that mission critical voice, data, control and management traffic links are maintained even if either the primary or the secondary T1 backhaul transmission links fail.  When the primary (working) link fails, the T1 traffic is automatically switched to the standby (secondary) link to ensure maximum uptime  Offers comprehensive remote configuration and alarm management capabilities of the SafeComm, 16 T1, 1+1 Automatic Protection Switching  Equipment the product may be used to improve network reliability and control  Increased network reliability through link resilience Features and Highlights: SafeComm 16 T1 Links (48 T1 Ports)

5. Slide 5 Orion Telecom Networks Inc. - 2010Slide 5  Media and Path Diversity  Remote Management  Alarm logging and monitoring  Dual -48V DC Power Inputs.  Loss of Signal  AIS (All Ones Alarm).  External Trigger” option - to switch between “primary” and “standby” T1 Links (the external trigger shall be a contact “open” or “closed” condition) User Programmable 1+1 Protection Switching Parameters: Features and Highlights: SafeComm 16 T1 Links (48 T1 Ports)

6. Slide 6 Orion Telecom Networks Inc. - 2010Slide 6 Salient Features:  SafeComm 1+1 Protection Switch does not "add" a point-of-failure to the T1 network.  Even in the event that the power to the SafeComm 1+1 Protection Switch (or the equipment itself) fails, the T1 link connectivity shall be "always" maintained." The T1 link integrity is ALWAYS maintained (the switch reverts the connection to the primary link), even if the power to the equipment is disconnected and removed. This ensures that the T1 link connectivity is never lost.  SafeComm 1+1 Protection Switch provides two power inputs and this allows the user to connect the switch to two separate independent - 48V DC power sources to minimize the chances of any power failure occurring due to power outage SafeComm 16 T1 Links (48 T1 Ports)
