EoSCU module (Ethernet over SDH Core Unit)
The two SDH interfaces and four Ethernet interfaces can be equipped with
optical and electrical SFPs.
STM-1 interfaces
• Up to two STM-1 interfaces per EoSCU, 1310 nm and 1550 nm (S1.1,
L1.1 and L1.2)
• Up to. 2 x STM-1 interfaces per EoSCU, electrical
STM-4 interfaces
• Up to 2 x STM-4 interfaces per EoSCU, 1310 nm and 1550 nm (S4.1,
L4.1 and L4.2)
Ethernet interfaces
• Up to 4 x Fast Ethernet interfaces per EoSCU
- 100Base TX electrical
- 100Base FX optical
- 100Base LX optical
E1 interfaces
• 6 external E1 interfaces, electrical, to ITU-T G.703 (unstructured and
structured to ITU-T G.704)
• 8 internal E1 interfaces to the PDH kernel, acc. to ITU-T G.704
CU-E sub-module (Control Unit Expansion)
The Central Unit Expansion (CU-E) sub-module is a pluggable expansion
for the Central Unit. It provides the control functions and management
interfaces to the SCUs (SDH Core Units) and EoSCUs (Ethernet over SDH
Core Units).
• Ethernet interface 10/100BaseT (RJ45 connector) for connecting the
network management system via a LAN infrastructure
• Computer for processing management functions
• ECC8 interface for communication with the ZAC-ASIC on the Central
Unit
• Internal bus interface for connection to the SCU/EoSCU
1.1.2.4 SDSL Line Equipment
ISHDSL module
• four SDSL interfaces acc. to ITU-T G.991.2
• four external E1 interfaces
• four internal E1 interfaces to XMP1 kernel
RPS-XMP1 Remote Power Supply module
• four Interfaces with Remote Supply Voltage -116 V
• Front cabling with ISHDSL module
