Base Transaction Unit Rules (E5-ENET-B IPSG High Throughput ON)

In addition to the rules specified in Base Transaction Unit Rules: IPLIMx, IPGWx, and IPSG (E5-ENET-B when IPSG High Throughput Feature OFF, E5-ENET), the following base transaction rules apply to E5-ENET-B IPSG cards when the E5-ENET-B IPSG High Throughput feature is turned on:

1. Number of links provisioned is less than or equal to 4
2. The average MSU size per second carried by IPSG links is less than or equal to 120 bytes.
3. The network round trip time (RTT) is less than or equal to 50 ms.
4. The traffic is carried by M2PA links.

For IPSG configuration exceeding these rules, additional TU adjustment costs as shown in Table 5-11 are enforced for deriving TUs consumed by a signaling link (SLK). If the derived TU cost exceeds the configured SLKTPS/MAXSLKTPS on an IPSG SLK, it will result in congestion of the link and discard of the MSUs.
