Part Number: 1181409L4
CLEI: SIAPPTVB_ _
- Used exclusively for Ethernet applications
- Works in combination with the Cell Switch Module (CSM), and Switch Module 2 (SM2)
- Delivers Ethernet services
- Complies with IEEE 802.3ah for up to eight DS1/E1 links
- Performs EFM bonding for up to eight DS1/E1 links
- Supports one to eight EFM Groups
- Supports from one to eight DS1/E1 interfaces in a single EFM Group
- Supports a maximum differential link delay of 16 ms
- Functions as network or subscriber side EFM connection in conjunction with an ATM CSM or frame based SM2
- Provides the upstream connection to a network Ethernet frame based switch
- Provides a downstream link to other subtended DSLAM systems
- Combines NxDS1 links into a single high-speed link to the ATM CSM or frame based SM2
- Continues operating (at a reduced rate) when a DS1/E1 link failure occurs, and automatically restores when the failure clears
- Provides a VT100 terminal menu interface for configuration, provisioning, status, test, and performance monitoring
- Communicates with a Controller Unit for management functions:
System Controller Unit (SCU)
Primary Controller Unit (PCU)
- Supports the download of new software via the Controller Unit
- Provides a 8 kHz system timing reference from any one of the eight DS1/E1 receive clocks
