EMM-E6 FEATURES

•BRIM-A6: 100/155 Mbps ATM Station connection with configurable connector.

The BRIM-A6 uses ATM Port Interface Modules (APIMs). APIMs allow a media flexibility for ATM connections like that provided by FPIMs (described above). The following APIM types are currently available:

•APIM-11: 100 Mbps multimode fiber optic SC connector

•APIM-21: 155 Mbps multimode fiber optic SC connector

•APIM-29: 155 Mbps single mode fiber optic SC connector

User Configurable EPIMs

The fourth channel (D) directs traffic to one of two external Ethernet Port Interface Modules (EPIMs). The following list contains the currently available EPIMs:

•EPIM-T: 10BASE-T RJ45 Port

•EPIM-F1: Sub-Miniature Assembly (SMA) connectors for multimode fiber optics

•EPIM-F2: Straight-Tip (ST) connectors for multimode fiber optics

•EPIM-F3: Straight-Tip (ST) connectors for single mode fiber optics

•EPIM-C: RG-58 connector for thin coaxial cabling

•EPIM-A: Female DB15 connector for AUI cabling

•EPIM-X: Male DB15 connector for AUI cabling

Expandable Flash EEPROM Memory

The EMM-E6 incorporates 2 MB of Flash Electrically Erasable Programmable Read Only Memory (Flash EEPROM). Flash memory holds the operating instruction code of the EMM-E6. When the module is activated, the instruction code (firmware) held in Flash memory is forwarded to Main memory, decompressed, and used to startup the EMM-E6. As the decompression of firmware slightly delays the initialization of the EMM-E6, a Flash memory upgrade is available that allows the firmware to be held in its expanded form.
