Orange Egypt (i.e. Mobinil) 1st and biggest mobile operator in Egypt 2G/3G/4G/LTE mobile operator Number of mobile BTSs: above 5000 sites Number of mobile subscribers: 35 million On October 14, 2016, Orange acquired its fourth-generation (4G) internet services

license after signing a 484 million USD agreement with the national telecom regulator Entity of Orange Group since 2012 100% shares


Oscilloquartz & ORANGE: Long-Term Relationship Oscilloquartz & Orange met in 1997 thanks to NEC

Heading Towards Carrier Ethernet Networks • Rapid deployment of small-cell solutions that are compatible only

with IP backhauling• Existing plan to shift all existing RAN to IP with accordance to IP-

2020 program.• In accordance with the above plan, transport network

deployments move from legacy SDH, PDH towards IP-MPLS network deployment• Existing TDM synchronisation using legacy PRC/SSU architecture

was no longer suitable


Network Restrictions and Explored Solutions• Backhauling capability to handle such small cell deployment is only through 3rd party HDSL (i.e. Telecom Egypt)• Part of IP-MPLS cloud is also 3rd Party with unknown PDV performance • Network is a PTP unaware network (brownfield network)

• SyncE Not suitable for such small cell deployment over HDSL, can only be used for macro site deployment• PTP 1588-V2 Suitable for small cell deployment but with unknown

performance over PTP unaware network/3rd party leased lines

Which solution for best sync performances: SyncE vs PTP?


Adopted Sync Solution

Proof of concept is necessary to validate achieved sync

performance over each scenario

Test 1: Macro node-B through MW link chain with ITUT G.82651 (frequency synchronization)

Test 2: Huawei ATOM cell through HDSL 3rd party (TE) with ITUT G.82671 (phase synchronization)

PTP 1588 -V2 Tests and Results


Conclusion• Successful testing and best approach determined and approved• Adopted product is OSA 5421

PTP delivery (freq and phase with 512 slaves capacity) with latest ITU-T standards

16X BITS outputs Sync probing or real-time monitoring included NTP server capabilities

• Solution currently under deployment (phases-based)• Ongoing 4G design and OSA 5421 may be massively deployed in future

ISA

Orange Egypt is satisfied with Oscilloquartz solutions as usual
