Wireless operators around the world are required to interconnect their Mobile Switching Centers (MSC) over expensive leased or owned circuits ranging from Microwave to SDH / SONET self-healing infrastructures. As business grows, the need to scale up their network to with maximum coverage places strains on multi-city mobile backbone networks. Sometimes, a Point of Interconnection (POI) interconnects the traffic to / from the local PSTN network in each of these cities - backhauled to the regional MSC - is also needed.
An efficient way to address this rapid growth is to deploy a toll quality voice compression solution to support traffic growth without expending the existing microwave infrastructure or leasing more bandwidth. By using Veraz's Wireless Network Compression solution, wireless operators are able to dramatically lower their operational costs by leveraging high quality compressed VoIP to transport calls when they are required to lease circuits.
The Veraz Wireless Network Compression solution combines the highest voice quality, including option to use cellular specific EFR codec, with the economies associated with VoIP. Moreover, Veraz's superior voice compression, as high as 12 to 1, enables carriers to reduce costs associated with leased lines, or meet rapidly rising traffic levels even when access to additional leased lines are constrained. Even more importantly, Veraz's platform voice quality and stability stand up under the most rigorous conditions: with superior handling of latency, jitter and packet loss, even over satellite links, it enables wireless carriers to deliver the high quality of service demanded by their customers.
PRINT THIS DIAGRAM 12:1 compression ratio for voice calls saves 92% of bandwidth cost for both POI backhauling and MCS to MSC applications- By compressing also the new traffic (the growing part), the existing infrastructure can support traffic growth of more than 1000%
- Maintaining toll quality voice compression by using G.729A compression algorithm, Silence Suppression, RTP aggregation and smart packets discarding techniques
- SCTP based transmission for SS7 channels provides
bandwidth saving and reliable communication for SS7 links
- Provides internal equipment redundancy (very short switch
over time) and link redundancy for the E-1 and STM-1 lines
- STM-1 and E1 interfaces using internal cross-connect function
to save additional network elements
- In-Band (bearer) management from centralized site
- High-quality alternative for multi- stage voice compression
using EFR compression algorithm
