We already brief of Outdoor part (MPT) and continue to show Indoor part.


Indoor Unit Part

FEATURE LIST
  • Fan-less Design, Temperature hardened -40 °C to +65 °C
  • 1+0, 1+1 radio protection, support of up to 6 MPTs
  • Multiservice Ring protection 8032 v2 support for access rings
  • 2 PFoE interfaces available for MPT-HC powering
  • 2+0 LAG L1: supported (HW ready)
  • Housekeeping IN/OUT management

b. MSS-4 and MSS-8


Compact, Modular Chassis:

  • MSS8: 2RU high, 19” width and 10” (300mm) depth, 8 flexible slots
  • MSS4: 1RU high, 19” width and 10” (300mm) depth, 4 flexible slots
  • 2 control module slots, 6 (or 2) half-wide I/O slots
  • Two feeds: -48/-60V DC, or optional integrated +24V DC/DC
  • Up to 24 radio directions for MSS8 and up to 12 radio directions for MSS4
  • High service reliability:
    • Fully protected, no single point of failure
    • Redundant core/switch modules
    • Redundant access cards
    • Distributed architecture for DC/DC converter (each card has its own DC/DC converter)
  • -40C to +65C operating temperature range

Component and MSS‐4/8 slots are reserved this way:
  • Slot 1 is dedicated to the Core Main Board
  • Slot 2 is dedicated to the Core Spare Board or to DC injector card
  • Slots 3‐8 are universal, reserved for transport and radio plug‐ins


Please note that for building protected radio links (with 2 radio access cards), the relevant boards have to be put on the same horizontal level, i.e. coupled on slots 3‐4, or 5‐6, or 7‐8.

Additional MPT interfaces

  • Up to 4 MPT support with optical connectivity
  • Multichannel LAG L1 for 2+0/3+0/4+0 configurations
  • Up to 24 MPTs supported in a single MSS8

5. Power injector plug-in


This card can be used for several applications:
  • When MPT is connected to CORE, power injector is needed to provide power to the MPT at optimized price
  • When MPT is used in stand alone (MPR‐e) and connected to 7705SAR, Power injector plug‐in can be used inside 7705 chassis to power MPT
A box version is also available for all other applications of MPR‐e.
Main physical characteristics:
  • 2 DC connectors in the front (box), or power from the backpanel.
  • 2 RJ45 for the data in
  • 2 RJ 45 for the data + DC out
  • 2 LEDs indicating the presence of DC voltage on each Ethernet output Power injector
