Abstract
A small broadband cross-connect system (10) includes a two-stage matrix (12) for processing and cross-connecting optical and electrical telecommunication network signals. An administration subsystem (14) provides centralized control and synchronization to the two-stage matrix (12). The two-stage matrix (12) may be expanded from 96 ports to 192 ports in a cost and space effective manner.
Claims28
A small broadband cross-connect system in a telecommunication network, comprising:
- a two-stage matrix for processing and cross-connecting broadband optical and electrical telecommunication network signals, said two-stage matrix including:
- a first high speed unit having first and second crosspoint switches, each cross-connecting signals at STS-1 rate;
- a second high speed unit having third and fourth crosspoint switches, each cross-connecting signals at STS-1 rate, said second high speed unit being interconnected with said first high speed unit;
- and
- a third high speed unit having fifth and sixth crosspoint switches, each cross-connecting signals at STS-1 rate, said third high speed unit being interconnected with said first and second high speed units;
- and
- an administration subsystem for providing centralized control and synchronization to said two-stage matrix.
A small broadband cross-connect system for cross-connecting high speed optical and electrical network signals in a telecommunication network, comprising:
- a two-stage matrix receiving, processing and cross-connecting broadband optical and electrical telecommunication network signals, said two-stage matrix including:
- a first high speed unit having first and second crosspoint switches, each cross-connecting signals at STS-1 rate;
- a second high speed unit having third and fourth crosspoint switches, each cross-connecting signals at STS-1 rate, said second high speed unit being interconnected with said first high speed unit;
- and
- a third high speed unit having fifth and sixth crosspoint switches, each cross-connecting signals at STS-1 rate, said third high speed unit being interconnected with said first and second high speed units;
- a redundant copy of said two-stage matrix also receiving, processing and cross-connecting broadband frequency level optical and electrical telecommunication network signals and functioning concurrently therewith and capable of being selected when needed;
- and
- an administration subsystem for providing centralized control and synchronization to said two-stage matrix.
