Local soft switch and method for connecting to and providing access to a TDM network
View Patent ↗A remote switch for connecting to and providing access to a TDM network. A switch resident of a non-TDM network implements control of various components in order to effectuate telecommunications in the non-TDM network. An access gateway at a remote location connects to the TDM network. The switch accesses the TDM network through the access gateway via the connection.
1. A remote switch for connecting to and providing IP access and services to a TDM network, comprising:
a first switch implemented in a non-TDM network for controlling various components in order to effectuate telecommunications in the non-TDM network;
an access gateway, at a remote location from the first switch, having a connection to the TDM network and handling TDM switching and networking for the first switch;
a processor incorporated in the first switch that provides communication adaptation between Ethernet and LAPD by performing protocol conversions using a stored mapping table;
communication channels connecting the first switch and access gateway, said communication channels obviating a need for TDM links between the TDM network and the first switch;
the first switch accessing the TDM network through the access gateway via the connection channels, to provide IP access and services to the TDM network;
the processor being assigned an MCP multicast address to participate in LAN monitoring; and
the first switch being configured to restrict trunk groups from crossing access gateway boundaries.
2. The remote switch according to claim 1 , wherein the switch offers call services and capabilities of the non-TDM network.
3. The remote switch according to claim 1 , wherein the switch is an IP switch.
4. The remote switch according to claim 1 , wherein the processor manages NSP-LTG message transport.
5. The remote switch according to claim 1 , wherein the access gateway includes at least one LTG.
6. The remote switch according to claim 1 , wherein the access gateway includes an RTI.
7. The remote switch according to claim 1 , wherein the access gateway includes a DLU.
8. The remote switch according to claim 1 , further comprising a user interface for interfacing a user to the switch.
9. The remote switch according to claim 1 , further comprising a lawful intercept processor for intercepting calls and forwarding them to a law enforcement operator.
10. A method for connecting to and providing IP access and services to a TDM network, comprising:
implementing control of various components using a switch in order to effectuate telecommunications in a non-TDM network;
accessing the TDM network through an access gateway remote to the switch connection to the TDM network;
handling TDM switching and networking for the switch by the access gateway;
providing communication adaptation at the switch between Ethernet and LAPD by performing protocol conversions using a stored mapping table, the communication adaptation being performed using a processor that is assigned an MCP multicast address to participate in LAN monitoring;
connecting the switch and access gateway through communication channels wherein the communication channels obviate a need for TDM links between the TDM network and the switch;
the switch accessing the TDM network through the access gateway via the connection to provide IP access and services to the TDM network;
the switch additionally restricting trunk groups from crossing access gateway boundaries.
11. The method according to claim 10 , further offering call services and capabilities of the non-TDM network.
12. The method according to claim 10 , wherein the switch is an IP switch.
13. The method according to claim 10 , further managing NSP-LTG message transport.
14. The method according to claim 10 , further interfacing a user to the switch.
15. The method according to claim 10 , further comprising intercepting calls and forwarding them to a law enforcement operator.
