Each rule specifies the action to take when a packet matches the specifies criteria. This section discusses the
rule actions and criteria supported by the system.
Rule Order: A single ACL can consist of multiple rules. Each packet is compared against each of the ACL rules,
in the order in which they were entered, until a match is found. Once a match is identified, all subsequent rules
are ignored.

ANSI T1.276 Compliance
ANSI T1.276 specifies security measures for Network Elements (NE). In particular it specifies guidelines for password
strength, storage, and maintenance security measures.
ANSI T1.276 specifies several measures for password security.
These measures include:
Password strength guidelines
Password storage guidelines for network elements
Password maintenance, e.g. periodic forced password changes
These measures are applicable to the systems and the Web Element Manager since both require password
authentication. A subset of these guidelines where applicable to each platform will be implemented. A known subset of
guidelines, such as certificate authentication, are not applicable to either product. Furthermore, the platforms support a
variety of authentication methods such as RADIUS and SSH which are dependent on external elements. ANSI T1.276
compliance in such cases will be the domain of the external element. ANSI T1.276 guidelines will only be implemented
for locally configured operators.
ATM VC Management Support
Support for Asynchronous Transfer Mode (ATM) virtual circuits (VC) management function of AAL2 and AAL5
protocol by the HNB-GW in accordance with the following standards:
3GPP TR 29.814 V7.1.0 (2007-06): 3rd Generation Partnership Project; Technical Specification Group Core
Networks and Terminals Feasibility Study on Bandwidth Savings at Nb Interface with IP transport (Release 7)
HNBGW supports PVC (permanent virtual circuits) connections with CN nodes for AAL2 and AAL5 type of traffic.
The Common Part Sublayer (CPS) payload which is carried out by the AAL2 protocol over ATM is also configurable
with this feature. It provides the dynamic Common Part Sublayer (CPS) payload configuration for AAL2 protocol
traffic over ATM for negotiation between HNB-GW and MSC during call. Default size for payload is 45 but values may
range from 1 to 64 Bytes. This feature makes the operator to choose the CPS payload size dynamically.
Congestion Control and Management Support
Congestion Control monitors the system for conditions that could potentially degrade performance when the system is
under heavy load. Typically, these conditions are temporary (for example, high CPU or memory utilization) and are
quickly resolved. However, continuous or large numbers of these conditions within a specific time interval may have an
