Configuration Management/Provisioning
Service Provisioning
NOTE:
A mix of services (V5.x and leased lines) on one E1 feeder is not possible.
V5 Protocol
V5 protocol is an ETSI (European Telecommunication Standards Institute) defined
interface protocol between a Local Exchange (LE) and an NE for the support of
the following access types:
■
Analogue telephone access: POTS (Plain Old Telephone Service)
■
ISDN Basic Rate Access: ISDN-BRA
■
Other analogue or digital accesses for permanent connections
with provisionable information channel allocation or flexible concentration capability within the NE.
NOTE:
ISDN Primary Rate Access will be possible in future releases.
Supported Subscribers
The general V5 protocol purpose is to connect PSTN (Public Switched Telephone
Network) and ISDN subscribers (via V5 Interface) and leased subscribers to the
LE. ETSI distinguishes between V5.1 Interfaces which only allow to connect
PSTN and ISDN-BRA subscribers and V5.2 Interfaces which allow to connect
ISDN PRA subscribers as well.
Cross-Connections
A single NE can contain a number of V5 User Ports, a number of V5 Interfaces
and a number of V5 Links (which represent 2,048 Mbit/s links). There is a bi-directional association (cross-connection) between each V5 Interface and all of its related V5 User Ports. Likewise there is a bi-directional relationship between each
V5 Interface and all its related V5 Links.

Cross-Connections
From the management point of view, a V5 Interface can be represented by a set of
logical manageable entities with their own configuration data and relations (crossconnections) that are established by provisioning.
Interfaces - Links
The NE may contains up to 16 V5 Interfaces and up to 16 V5 Links (16 E1 physical feeders limitation). On the other hand, for AnyMedia Access System a limitation of 512 subscribers (V5 User Ports) arises from the 32-channel POTS APs.
