EMM-E6 Ethernet User's Guide

EMM-E6 FEATURES
EMM-E6 User’s Guide 1-7
• 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.
