AAL2 Establish and Release Support

Support to establish and release of ATM adaptation layer 2 (AAL2) channel within an ATM virtual connection by the
HNB-GW in complete or partial compliance with the following standards:
 3GPP TS 25.414 V9.0.0 (2009-12): 3rd Generation Partnership Project; Technical Specification Group Radio
Access Network; UTRAN Iu interface data transport and transport signalling (Release 9)
 3GPP TS 25.415 V8.0.0 (2008-12): 3rd Generation Partnership Project; Technical Specification Group Radio
Access Network; UTRAN Iu interface user plane protocols (Release 8)
 3GPP TS 25.467 V8.0.0. (2008-12): 3rd Generation Partnership Project; Technical Specification Group Radio
Access Network; UTRAN architecture for 3G Home NodeB; Stage 2 (Release 8)
 3GPP TS 25.467 V9.1.0 (2009-12): 3rd Generation Partnership Project; Technical Specification Group Radio
Access Network; UTRAN architecture for 3G Home Node B (HNB); Stage 2 (Release 9)
 ITU-T Recommendation Q.2630.1: AAL type2 signalling protocol (Capability Set 1)
 ITU-T Recommendation Q.2630.2: AAL type2 signalling protocol (Capability Set 2)
 ITU-T Recommendation I.363.2 B: ISDN ATM Adaptation Layer (AAL) Specification: Type 2 AAL
 ITU-T Recommendation I.366.1: Segmentation and Reassembly Service Specific Convergence Sublayer for
the AAL type 2
The HNB-GW connects to core network elements like MSC and SGSN over IuCS and IuPS interfaces respectively. The
Iu interface towards core network elements could either by IP based or ATM based. To provide ATM based interface
support, Cisco HNB-GW provides AAL2 support on system in order to establish a voice bearer with MSC.

Access Control List Support

Access Control Lists provide a mechanism for controlling (i.e permitting, denying, redirecting, etc.) packets in and out
of the system.
IP access lists, or Access Control Lists (ACLs) as they are commonly referred to, are used to control the flow of packets
into and out of the system. They are configured on a per-context basis and consist of "rules" (ACL rules) or filters that
control the action taken on packets that match the filter criteria
Once configured, an ACL can be applied to any of the following:
 An individual interface
 All traffic facilitated by a context (known as a policy ACL)
 An individual subscriber
 All subscriber sessions facilitated by a specific context
There are two primary components of an ACL:
 Rule: A single ACL consists of one or more ACL rules. As discussed earlier, the rule is a filter configured to
take a specific action on packets matching specific criteria. Up to 128 rules can be configured per ACL.
