Abstract
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.
Claims15
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.
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.
