1. PRODUCT DESCRIPTION
1.1.Description
The Loop-IP6702A device allows operators to transport Unframed/Framed 1 E1 (1 Unframed/Framed
T1) data stream with timing information over PSN (Packet Switched Network) via Pseudowire
Protocol –SAToP or CESoPSN . Another IP6702A converts the received packet stream back to
original E1 or T1 data stream with original timing information. This allows cost-effective migration from
existing legacy TDM networks to Packet Switched Network.

2. INSTALLATION
2.1.Site Selection
The following list indicates a site selection guideline. Users need to follow this guideline to select a
proper installation site.
Location of the Loop-IP6702A unit should be part of the central office equipment layout design.
Considerations should be given to entrance cable routing.
The installation site should provide proper room for adequate ventilation and cable routing. Reserve at
least 0.5 m at the rear of the unit for human access, cables, and air flow.
The site should provide a stable environment. The operating area should be clean and free from
extremes of temperature, humidity, shock, and vibration.
Relative humidity should stay between 0 and 95%.

Chassis Grounding
The chassis is grounded when rack mounted. However, for stand alone units or extra grounding
protection for rack mounted units, a dedicated chassis ground screw and lock washer is provided. The
chassis ground screw is located on the right side of rear panel.
When attaching a ground wire to the chassis ground screw, please follow these instructions:
 Use copper grounding conductors of 18 AWG
 Conductors should not be of dissimilar metals.
 The bare conductors should be coated with anti-oxidant before crimp connections are made.
 Unplanted connection surfaces, connectors, braided strap and bus bars must be bought to a bright
finish and coated with anti-oxidant before connections are made.
 Listed connectors and fastening hardware must be used.
