Interface and Port Engineering Rules
The rules discussed in this section pertain to both the Ethernet 10/100 and Ethernet 1000 Line Cards and the four-port
Quad Gig-E Line Card and the type of interfaces they facilitate.
IuCS Interface Rules
When supporting CS networks, the system can be configured to provide IuCS interface support and connects to the
MSC in a CS network in same the PLMN.
The following engineering rules apply to the IuCS interface between the HNB-GW and MSC:
An IuCS interface is created once the IP address of a logical interface is bound to a CS Network service.
The logical interface(s) that will be used to facilitate the IuCS interface(s) must be configured within the egress
context.
CS Network services must be configured within the egress context.
Multiple MSCs (maximum 25) can be configured through IuCS interfaces within the HNB-GW service instance.
IuPS Interface Rules
When supporting PS networks, the system can be configured to provide IuPS interface support and connects to the
SGSN in a PS network in the same PLMN.
The following engineering rules apply to the IuPS interface between the HNB-GW and SGSN:
An IuPS interface is created once the IP address of a logical interface is bound to a PS Network service.
The logical interface(s) that will be used to facilitate the IuPS interface(s) must be configured within the egress
context.
PS Network services must be configured within the egress context.
Multiple SGSNs (maximum 25) can be configured through IuPS interfaces within the HNB-GW service
instance.
