- Successfully Completes EANTC Multi-Vendor Mobile Backhaul 
Interoperability Tests

Celtro, the leading supplier of innovative mobile backhaul
switching solutions, today announced that it successfully completed
multi-vendor interoperability tests performed at the independent European
Advanced Networking Test Center (EANTC). In the course of the testing,
Celtro's DMT1000 and DMT4000 were found to be interoperable with other
leading vendor equipment in an IP/MPLS mobile backhaul network scenario.

Tested together in a live network which consisted of more than
75 different devices over a two-week hot staging period at EANTC's lab in
Berlin, Germany last month, Celtro's DynaMate(TM) mobile switching solutions
were rigorously tested for:

- Synchronization - Maintaining precise clock synchronization
in packet-based network. Celtro's DynaMate solutions successfully completed
the precision time (IEEE 1588v2) and Synchronous Ethernet tests, and are
viable for mobile base station and Node B synchronization.

- PWE Based on T-LDP Signaling -DynaMate solutions
successfully demonstrated interoperability with ATM (RFC 4717), and TDM (RFC
5086) PWE using the LDP/T-LDP signaling protocol.

"We were honored to participate in the interoperability tests,
and for the opportunity of demonstrating Celtro's IP/MPLS functionality and
interoperability," said Ariel Shuper, Senior Director and Head of Product
Management and Strategy at Celtro. "By testing the interoperability of multi
vendors, EANTC is furthering the adoption of IP/MPLS solutions in mobile
backhaul networks - which is good for both vendors and operators," he
concluded.

"We were pleased to include Celtro's DynaMate solutions in the
IP/MPLS backhaul network testing," noted Carsten Rossenhoevel, Managing
Director at EANTC. "Adoption of standards by vendors like Celtro is key to
growing the IP/MPLS industry as a whole," he continued.

Celtro has already deployed its IP/MPLS solutions in select
leading mobile operators, converging both 2G and 3G/HSPA traffic.
