Traffic Handling - QoS Provisioning with ARP
The SGSN now enables setting the priority of service via the configuration of the
allocation/retention priority (ARP) IE. By including this IE in the RANAP message during
the RAB assignment procedure it is possible to specify the relative importance of the radio
access bearers for the allocation and retention of traffic. When there is a resource crunch,
the IE is used by the RNC to allocate or deallocate resources according to the defined
priority. This IE also tells whether queuing of packets is allowed or not.

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:

CLC2 - Channelized Line Card 2
For Frame Relay signaling, the SGSN now supports the Channelized Line Card 2 (CLC2),
the next-generation SONET/SDH channelized line card for the ST40. 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 ST40 Hardware Installation and Administration
Guide.

OLC2 - Optical Line Card 2
For ATM signaling, the SGSN now supports the Optical Line Card 2 (CLC2), the
next-generation SONET/SDH optical line card for ATM signaling on the ST40. The OLC2
supports all features, including 4 ports, available on the original OLC but now includes
RoHs 6/6 compliance. For more information about this card, refer to the ST40 Hardware
Installation and Administration Guide.
