• MPT-MC (MPR-E)
The ODUs are connected to an Ethernet generic device, and the ways to connect it to the
Ethernet generic Device. The Ethernet generic device implements L2/L3 functionalities.
The Ethernet generic Device is a device with the prerequisites listed in Ethernet generic
device prerequisites.
Several portions of this document focus on 7705 SAR family because additional features
are supported when the MPR-e is connected to a 7705 SAR device. Paragraph 7705 SAR
platform prerequisites illustrates the prerequisites of the 7705 platform to make use of these
features.
3.1.3 — MSS-1c
The MSS-1c provides user port interface, cross-connection and switching management.
The cross-connection matrix implements all the cross-connections between the User ports
(4 Ethernet ports and E1/T1 streams) and the Radio port. The matrix is a standard Ethernet
switch, based on VLAN, assigned by the MCT.
The E1/T1 enter the LIU and then the IWF, which manages the encapsulation and
reconstruction of PDH data to and from standard Ethernet packets and sends and receives
standard Ethernet packets to and from the Ethernet switch.
Two variants of MSS-1c are available:
• MSS-1c providing 10E1 and 4 User Ethernet ports
• MSS-1c 16PDH providing 16E1 or 16T1 and 4 User Ethernet ports. This version is
HW ready to manage up to 2 STM-1 frames (instead of 2 Ethernet ports) not
supported by the current SW Release
The Radio Interface interfaces the MPT-HC or MPT-HC or MPT-HC-HQAM, or the MPT-
MC (MPR-E) or MPT-XP, MPT-XP-HQAM or 9558HC (MPR-A).
The radio interface is a standard GbEth interface: electrical only for MPT-MC (MPR-E)
and electrical or optical for MPT-HC, MPT-HC, MPT-HC-HQAM, MPT-XP, MPT-XP-
HQAM, and 9558HC (MPR-A). It sends/receives standard Ethernet packets to/from the
Ethernet switch.
