  2. E1 Protection Switching Equipment PRODUCT 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.

  3. E1 Protection Switching Equipment FEATURES & HIGHLIGHTS • 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. APPLICATIONS • Providing 1+1 alternate paths between any two Transmission medium (active+standby). • e.g:- • ! Fiber / Fiber. • ! Radio / Fiber. • ! Radio / HDSL • ! Fiber / HDSL etc. Confidential Slide 3
