Hello

The EG4 board is mainly used to access the user GE data. It can be considered as the signal input end. 

The ISV3 board transmits user-accessed data, such as data received from an EG4 board, to an ODU through an IF port. The ODU then transmits the data to its peer equipment.

Hi user hope below can help:

Hello,

ISV3

• • Version Description

  • The functional version of ISV3 boards is SL91.

  • Application

  • ISV3 boards function as SDH IF boards to transmit SDH radio services, or as Integrated IP microwave IF boards to transmit Integrated IP microwave services (native E1+Ethernet or native STM-1+Ethernet). If transmission capacity needs to be expanded, XPIC can be used.

  • Functions and Features

  • The ISV3 board receives and transmits one channel of IF signals, provide a management channel to the ODU, and supplies -48 V power to the ODU. When the XPIC function is enabled, the ISV3 board also implements XPIC for IF signals by transmitting and receiving XPIC reference signals.

  • Working Principle and Signal Flow

  • This section describes how the function units of an ISV3 board process Integrated IP microwave IF signals.

  • Front Panel

  • An ISV3 board has indicators, XPIC signal ports, one IF port, one ODU power switch, and labels on its front panel.

  • Valid Slots

  • The ISV3 board can be inserted in Slots 1 to 6, which have consistent logical slot numbers on the NMS.

  • Technical Specifications

  • This section describes board specifications, including running modes, radio working modes, IF performance, modem performance, mechanical behaviors, and power consumption.

EG4/EG4P

• • Version Description

  • The functional version of EG4/EG4P boards is SL91.

  • Application

  • EG4/EG4P boards receive and transmit GE services or carry Multiprotocol Label Switching (MPLS) tunnels. Because one EG4P board provides two power-over-Ethernet ports, EG4P boards can also build networks in conjunction with OptiX RTN 310/380.

  • Functions and Features

  • EG4/EG4P boards receive/transmit, process, and converge 4xGE service signals. They also can receive/transmit 2xFE optical signals using FE SFP optical modules installed at their SFP ports.

  • Working Principle and Signal Flow

  • This section describes how the function units of an EG4/EG4P board process GE signals.

  • Front Panel

  • An EG4/EG4P board has indicators, GE service ports, and a power caution label on its front panel.

  • Valid Slots

  • The EG4/EG4P board can be inserted in Slots 1–6, which have consistent logical slot numbers on the NMS.

  • Types of SFP Modules

  • FE/GE SFP ports on EG4/EG4P boards support multiple types of SFP modules.

  • Technical Specifications

  • This section describes board specifications, including the Ethernet service port performance, power-over-Ethernet performance, mechanical behaviors, and power consumption.

Thanks

Hello,

Valid Slots

The ISV3 board can be inserted in Slots 1 to 6, which have consistent logical slot numbers on the NMS.

For the maximum number of boards supported by the OptiX RTN 950A, see Number of radio directions in Product Description.

Figure 1 Physical slots for ISV3 boards in a chassis

An ODU does not occupy a physical slot but has a logical slot on the NMS. The logical slot ID of an ODU is equal to the logical slot ID of the connected IF board plus 20.

Figure 2 Logical slots of ISV3 boards on the NMS

Table 1 Slot allocation

Item	Description
Slot allocation priority	Slots 3 and 5 > Slots 4 and 6 > Slots 1 and 2

Two IF1 boards can be configured as a 1+1 FD/SD protection group only when being housed in two paired slots: Slots 1 and 2, Slots 3 and 5, or Slot 4 and 6.

When forming an XPIC group, the two ISV3 boards must be inserted in two adjacent slots in the same row or column. For details, see Planning Guidelines (XPIC) in Feature Description.

Valid Slots

The EG4/EG4P board can be inserted in Slots 1–6, which have consistent logical slot numbers on the NMS.
