E1 Protection Switching EquipmentE1 Protection Switching Equipment

PRODUCT OVERVIEWPRODUCT OVERVIEW

•E1 Protection Switching System provides

point to point 1+1 redundancy link support

between any 2 independent E1 ports or 2

groups of E1 ports connected via higher order

multiplexers.

• Each E1 redundancy switch (each E1 Switch card) supports one E1 link

• Upto 16, E1 links can be supported by a "pair" of E1 Protection Switching Systems. Two E1 Protection Switching Systems are required (one at each end of the link) for implementation of 1+1 redundancy solution.

• One E1 Protection Switching System must be configured as "Master" and installed at one end of the E1 link.

• The other E1 Protection Switching System must be configured as “Slave” and installed at the corresponding far end of the E1 link.

• Provides 1+1 E1 redundancy link (active+standby) between any two complementing transmission mediums.

• Provides 1+1 E1 redundancy support to higher order multiplexers eg. E2, E3.

• System configuration & management interface through "CLI" text based commands.

FEATURES & HIGHLIGHTSFEATURES & HIGHLIGHTS

• Providing 1+1 alternate paths between any two Transmission medium (active+standby). e.g:-

Fiber / Fiber.
