Since HSL is using ATM Bundling technology, they create one tunnel
containing 30 time slots to achieve the 2 Mbps link speed. (30 * 64 = 1920) is
the actual available bandwidth for the signaling traffic.
Nowadays both NSN & HUAWEI support the bundling of 8 time slots to one HSL Link. So that they can use the remaining time slots for some other purpose/links. For an example in Huawei they can map some of the incoming signaling link to another PCM without even doing any MTP3 level analysis.
Even though number of SIGTRAN deployments are growing fast, but still HSL will exist for a while till the IP-fication completes everywhere.
The traditional Narrow-band / LSL C7 Link Set capacity was 16 Links * 64 Kbps = 1024 Kbps.Where using HSL technology we can achieve a capacity of 16 Links * 1920 Kbps = 30 Mbps capacity.
