Although the HLR subscription record only provides a single priority parameter (values 0 to 3), the RNC needs
additional information, which our configuration command maps to the subscription priority. Additional information
needed:
additional information, which our configuration command maps to the subscription priority. Additional information
needed:
Priority Level: 1..15
Pre-emption Capability Indicator (PCI): shall-not-trigger-pre-emption, may-trigger-pre-emption
Pre-emption Vulnerability Indicator (PVI): pre-emptable, not-pre-emptable
Queuing Allowed: queuing-not-allowed, queuing-allowed

Data Rate Management per RNC
Configurable control of data rates on a per RNC basis enables operators to allow subscribers to roam in and out of
coverages areas with different QoS levels.
coverages areas with different QoS levels.
The SGSN can now limit data rates (via QoS) on a per-RNC basis. Some RNCs support HSPA rates (up to 16 Mbps in
the downlink and 8 Mbps in the uplink) and cannot support higher data rates - such as those enabled by HSPA+
(theoretically, up to 256 Mbps both downlink and uplink). Being able to specify the QoS individually for each RNC
makes it possible for operators to allow their subscribers to move in-and-out of coverage areas with different QoS
levels, such as those based on 3GPP Release 6 (HSPA) and 3GPP Release 7 (HSPA+).

For example, when a PDP established on an RNC with 21 Mbps is handed off to an RNC supporting only 16 Mbps, the
end-to-end QoS will be re-negotiated to 16 Mbps. Note that an MS/UE may choose to drop the PDP during the QoS
renegotiation to a lower value.

This data rate management per RNC functionality is enabled, in the RNC configuration mode, by specifying the type of
3GPP release specific compliance, either release 7 for HSPA+ rate or pre-release 7 for HSPA rates. For configuration
details, refer to the RNC Configuration Mode chapter in the Command Line Interface Reference (version 8.x).

CLC2 - Channelized Line Card 2
New in release 8.1, the SGSN supports the Channelized Line Card 2 (CLC2), the next-generation SONET/SDH
channelized line card for Frame Relay signaling on the ASR 5000.
channelized line card for Frame Relay signaling on the ASR 5000.
In North America, the card supplies ANSI SONET STS-3 (optical OC-3) signaling. In Europe, the card supplies SDH
STM-1 (optical OC-3). The transmission rate for the card is 155.52 Mb/s with 336 SONET channels supplying T1 and
252 SDH channels supplying E1. The CLC2 is RoHs 6/6 compliant. Each CLC2 provides four optical fiber physical
interfaces (ports). For more information about this card, refer to the ASR 5000 Hardware Installation and
Administration Guide.
