ETH
The ETH (Ethernet Interface) Module provides 10 Base-T and 100
Base-T Auto-Negotiation Interfaces. ETH conforms to IEEE
802.3 Ethernet and IEEE 802.3u Fast Ethernet standard
regulations, and supports Full Duplex and Half Duplex
transmission. ETH provides Rate Limiting functions, and it can
support a transmission distance of up to 100 meters with Cat-5
UTP 10 copper cables. With a RJ-45 connector, its frequency
width can be configured to start at 1 Mbit/s, and increased up to 16
Mbit/s, at 1 Mbit/s per step. The final error rate is less than 10%.
ESM
ESM is an 8 port LAN switch Module; each module provides 8
IEEE 802.3 10/100 Auto-Negotiation Ethernet interfaces. ESM
supports IEEE802.1d STP, 802.1p, Port-based & tag-based
VLAN, and Static MAC address filtering.
AAM
The ADSL Access Module (AAM) provides 12 lines of ADSL
subscriber interfaces, and supports ITU-T G.992.1, G.992.2, ANSI
T1.413 issue 2, ADSL2 (G.992.3, G.992.4), ADSL2+(G.992.5),
ITU-T G.994.1 specifications. AAM is IP-based, and it supports
802.3/3u/3x 100 Mbps Ethernet frequency width. AAM provides
VLAN, GVRP, IGMP snooping, PPPoE and DHCP functions.
Maximum number of ADSL subscriber lines per shelf is 96 while
maximum number of ADSL subscriber lines per shelf is 576.
