Making the move from SS7 to SIGTRAN

By Alan Percy, CMO @TelcoBridges

Over the last year, we’ve seen an increasing trend where service providers across North America are modernizing their networks, moving from TDM-based SS7 signaling to IP-based SIGTRAN.   We recently published a new solution brief titled “Migrating from SS7 to SIGTRAN”.   The brief explains some of the motivation for moving from SS7 to SIGTRAN, much of which is driven by the expense and difficulty in maintaining the long-distance DS1 circuits that interconnect the service providers with their interconnect peers.  Spoiler alert: SIGTRAN’s IP infrastructure is more cost effective and reliable.

Earlier this week, Transaction Network Service (TNS), an infrastructure-as-a-service company and partner of TelcoBridges, announced their TDM Link Replacement Service (TLR), helping service providers making the transition from SS7 to SIGTRAN.

As noted by Bill Versen, TNS’ President, Communications Market

many Tier 2 and Tier 3 carriers are still faced with the risky, costly and complex migration to IP based connectivity solutions to replace their legacy TDM equipment.

Versen also points to another benefit to migrating to SIGTRAN – the implementation of SIP and STIR/SHAKEN:

Deploying our new TLR solution enables them to keep their legacy equipment and also delay changing their network to full IP, yet still achieve STIR/SHAKEN compliance along with Call Guardian, our leading analytics and call verification system”.

Based on our meetings with many mid-market and rural operators, there is a lot of SS7 equipment hidden away in switch rooms across the US and Canada.   We believe migrating to SIGTRAN is a natural next step for many of these operators.
