3DB18809AAAA Issue 1 49/980
The Spare Core-E is an optional unit to provide aggregated traffic protection and control platform
protection.
The following Transport modules are supported:
– TDM 32E1/DS1 local access module: provides the external interfaces for up to 32xE1 tributaries,
manages the encapsulation/reconstruction of PDH data to/from standard Ethernet packets and
sends/receives standard Ethernet packets to/from both Core-E modules; it contains the switch for
the EPS Core-E protection and the DC/DC converter unit.
– STM-1 local access module: provides the external interfaces for up to 2 electrical or optical STM-
1 signals, manages the encapsulation/reconstruction of SDH data to/from standard Ethernet packets
and sends/receives standard Ethernet packets to/from both Core-E modules; it contains the switch
for the EPS Core-E protection and the DC/DC converter unit.
– ASAP module: provides the external interfaces for up to 16xE1 tributaries carrying ATM cells,
manages the encapsulation/reconstruction of ATM cells (according to the PWE3 standard) to/from
standard Ethernet packets and sends/receives standard Ethernet packets to/from both Core-E
modules; it contains the DC/DC converter unit.
– ODU300 Access module: this module is used to interface one ODU300. It sends/receives standard
Ethernet packets to/from both Core-E modules, manages the radio frame (on Ethernet packet form)
generation/termination, the interface to/from the alternate Radio module (for RPS management), the
cable interface functions to ODU; it contains the logic for the EPS Core-E protection, the RPS logic
and the DC/DC converter unit.
For each radio direction with ODU300, one ODU300 Access module in the MSS and one associated
ODU300 has to be provisioned in case of 1+0 radio configuration. Two radio access modules and
two associated ODU300 have to be provisioned in case of 1+1 radio configurations.
– MPT Access (with PFoE) module: this module is used to interface up to two MPT-HC or the MPT-
MC. This module provides the Power Feed over Ethernet to the MPT (only one cable to carry
Ethernet traffic and power supply). The interface to the MPT-HC is a standard GbEth interface
(electrical or optical) and a power supply cable. The interface to the MPT-MC is a standard GbEth
interface (electrical). It sends/receives standard Ethernet packets to/from both Core-E modules. It
contains the logic for the EPS Core-E protection and the DC/DC converter unit.
For each radio direction with MPT, one MPT Access module in the MSS and one associated MPT
has to be provisioned in case of 1+0 radio configuration. One (or two) MPT Access modules and two
associated MPT have to be provisioned in case of 1+1 radio configurations.
– EAS Peripheral (P8ETH) module: provides access for customer Ethernet traffic.
It supports the following traffic external interfaces:
• 4xEthernet 10/100/1000 Base-T
• 4xEthernet SFP 4x1000 Base-X optical, Base-T, or Copper Cable access directly available on
the EAS module. Interfaces can be 1000BASE-LX (GbE LX 10 km) or 1000BASE-SX (GbE SX
550 m) or 1000BASE-CX (GbE CX 25 m)
According to the transport modules installed different configurations can be implemented.
The optional AUX peripheral module provides 2x64 kbit/s service channels and the housekeeping
alarms.
The optional +24 Vdc/-48 Vdc Converter module (to be installed in transport slot 4, 6 or 8 for MSS-8 and
in transport slot 3 or 4 for MSS-4) can be used to power supply the MSS for +24 Vdc office applications.
A simplified block diagram of the MSS is shown in Figure 8. for MSS-8 and in Figure 9. for MSS-4.
