1830 TPS

Overview

The 1830 TPS provides ultra-low-latency transport between cell sites and edge hub sites. RAN-agnostic multiservice transport of CPRI, RoE, eCPRI and Ethernet traffic streams on one platform ensures minimized latency and high-precision timing. NFM-P support for the 1830 TPS includes configuring Radio over Ethernet and structure-aware mapping for ports on 1830 TPS nodes.

The NFM-P supports equipment configuration and statistics collection on 1830 TPS nodes. For information about configuring TCA monitoring on the 1830 TPS, see To create an 1830 TPS TCA policy; for information about configuring routing instances on the 1830 TPS, see To configure Ethernet interfaces, DHCP servers, and DHCP relays on 1830 TPS routing instances.

Note: Read-only parameters displayed in equipment forms are not renewed automatically, and the form must be refresh manually to retrieve updated information.

Structure-aware mapping

Radio over Ethernet (RoE) provides a method to encapsulate the CPRI frames from REC/BBU to RE into Ethernet frames transported across Ethernet Switches or Bridges in the fronthaul network. RoE supports different mapping modes to allow better network transport efficiency. In structure-aware mapping mode, the RoE mappers are partially aware of the structure of the CPRI basic frames; they selectively extract control words and AxC containers and container groups. In this mode, the system allows multiple RoE mappers created for one CPRI port. Each BBU connecting to a CPRI port supports a certain number of AxC (Antenna Carriers) based on the RU type. Each antenna supports certain bandwidth ranging from 1.4 to 20 MHZ.

The NFM-P acts as an NBI interface to fetch the relevant data from the BBU and perform the necessary configurations on the 1830 TPS to enable mapping. For information about configuring structure-aware mapping using the NFM-P, see 1830 TPS interoperation with AirScale BBU.
