Abstract
Systems and methods for handling different types of alarm signals, such as red, blue, and/or yellow alarm signals, in hybrid time division multiplexing (TDM)/asynchronous transfer mode (ATM) networks. A terminal adapter, which may be in the form of a stand-alone device and/or integrated with an ATM switch, may receive an alarm signal from a TDM switch. Based on the nature of the alarm signal, the terminal adapter may send a message to the ATM switch and/or acknowledge to the TDM switch that the terminal adapter has received the alarm signal from the TDM switch. The ATM switch, upon receiving the message from the terminal adapter, may route appropriate other messages to other ATM switches and/or TDM switches in the hybrid network. Other ATM
switches receiving such messages may in turn route appropriate messages via the signaling network to other ATM switches and/or TDM switches.
switches receiving such messages may in turn route appropriate messages via the signaling network to other ATM switches and/or TDM switches.
Claims (23)
1. A method comprising the step of generating a first alarm message in an asynchronous transfer mode (ATM) network responsive to receiving a time division multiplexing (TDM) alarm signal.
2. The method of claim 1 wherein the TDM alarm signal is a Blue alarm signal.
3. The method of claim 1 wherein the TDM alarm signal is a Yellow alarm signal.
4. The method of claim 1 wherein the TDM alarm signal is a loss of signal.
5. The method of claim 1 wherein the first alarm message is an ATM
user-to-network signaling message.
user-to-network signaling message.
6. The method of claim 1 further including the step of routing a second alarm message associated with the first alarm message through the ATM network.
7. The method of claim 6 wherein the second alarm message is a "BLOCKED
STREAM" message.
STREAM" message.
8. The method of claim 6 wherein the second alarm message is a "BLOCKED
TRUNK" message.
TRUNK" message.
9. The method of claim 6 wherein the second alarm message is the first alarm message.
10. The method of claim 1 wherein the TDM alarm signal is generated by a first TDM switch associated with an alarmed trunk, the method further including the step of sending a second alarm message associated with the first alarm message to a second TDM
switch, wherein the second TDM switch marks the alarmed trunk as out of service responsive to receiving the second alarm message.
switch, wherein the second TDM switch marks the alarmed trunk as out of service responsive to receiving the second alarm message.
11. In an asynchronous transfer mode (ATM) network, a method comprising the step of generating a time division multiplexing (TDM) alarm signal responsive to a disruption occurring in the ATM network.
12. The method of claim 10 wherein the TDM alarm signal is a Blue alarm signal.
13. The method of claim 10 wherein the TDM alarm signal is a Yellow alarm signal.
14. An apparatus configured to be connected to a TDM network, the apparatus comprising:
a time division multiplexing (TDM) interface configured to be connected to the TDM network and further configured to generate a first signal responsive to receiving a TDM alarm signal from the TDM network;
a processor connected to the TDM interface and configured to generate a second signal responsive to receiving the first signal; and an asynchronous transfer mode (ATM) interface connected to the processor and configured to generate an ATM alarm message responsive to receiving the second signal.
a time division multiplexing (TDM) interface configured to be connected to the TDM network and further configured to generate a first signal responsive to receiving a TDM alarm signal from the TDM network;
a processor connected to the TDM interface and configured to generate a second signal responsive to receiving the first signal; and an asynchronous transfer mode (ATM) interface connected to the processor and configured to generate an ATM alarm message responsive to receiving the second signal.
15. The apparatus of claim 14 wherein the TDM alarm signal is a Blue alarm signal.
16. The apparatus of claim 14 wherein the TDM alarm signal is a Yellow alarm signal.
17. The apparatus of claim 14 wherein the TDM alarm signal is a loss of signal.
18. The apparatus of claim 14 wherein the ATM alarm message is an ATM
user-to-network signaling message.
user-to-network signaling message.
19. The apparatus of claim 14 wherein the apparatus is configured to be incorporated into an ATM switch.
20. The apparatus of claim 14 further including a memory connected to the processor, wherein the processor is further configured to log the TDM alarm signal in the memory.
21. An apparatus configured to be connected to an ATM network, the apparatus comprising:
an asynchronous transfer mode (ATM) interface connected to the processor and configured to generate a first signal responsive to detecting a disruption in the ATM
network;
a processor connected to the ATM interface and configured to generate a second signal responsive to receiving the first signal; and a time division multiplexing (TDM) interface connected to the processor and configured to generate a TDM alarm signal responsive to receiving the second signal.
an asynchronous transfer mode (ATM) interface connected to the processor and configured to generate a first signal responsive to detecting a disruption in the ATM
network;
a processor connected to the ATM interface and configured to generate a second signal responsive to receiving the first signal; and a time division multiplexing (TDM) interface connected to the processor and configured to generate a TDM alarm signal responsive to receiving the second signal.
22. The method of claim 10 wherein the TDM alarm signal is a Blue alarm signal.
23. The method of claim 10 wherein the TDM alarm signal is a Yellow alarm signal.
