AUSM-8T1/E1

AUSM-8T1/E1

The AUSM-8T1/E1 is a multipurpose card that supports up to 8-T1 or E1 ports and can be used for the following four MGX 8220 applications:

1.ATM Inverse Multiplexing nxT1 and nxE1 trunking

This application supports inverse multiplexed trunks between MGX 8220 shelves. In turn, this supports inverse multiplexed trunks between BPX 8620 and the IGX network nodes via MGX 8220 shelves and remote MGX 8220 shelves.

2.ATM UNI card with eight ports to provide a high port density service module

With all ten available slots installed with the AUSM-8T1/E1 cards, a single MGX 8220 shelf could support up to 80 individual T1/E1 lines.

In UNI/NNI mode each card can support 1000 data connections and 16 management connections. In STI format, each card can support 100 virtual paths.

3.UNI/NNI access to CPE and other Networks

This application allows access over an UNI to IMA-based CPE and over an NNI to another ATM network.

4.NNI/NNI access to CPEs

This application supports ATM ports over single T1/E1 line and IMA ports over multiple

T1/E1lines (connected to IMA based CPE).

The following back cards are compatible with the AUSM-8T1/E1:

•RJ48-T1 back card for T1

•RJ48-E1 back card for E1

•SMB-E1 back card for E1

The 4-port AUSM back cards and IMATM backcards are not compatible with the AUSM-8T1/E1.

The AUSM-8T1/E1 has the following features:

•Statistics collection.

•Support for VP connections.

•Support for BERT functionality with loopback pattern generation/verification on individual T1/E1 lines.

•1:N redundancy with active and standby AUSM-8T1/E1 modules.

•Auto-card restore.

•Compatible with SRM-3T3.
