TCU Description
› The TCU (Transport Connectivity Unit) is a component in the RBS 6000 product family and has been designed primarily to support Multi Standard RBS with advanced transport functionality.
TCU Upgrade | Ericsson Internal | 2012-11-03 | Page 4
TCU Description
› TCU provides the converged cell site with advanced transport functions, aggregating traffic from multiple digital units into One Pipe - a single, resilient IP interface for GSM, WCDMA, and LTE traffic
TCU Upgrade | Ericsson Internal | 2012-11-03 | Page 5
TCU Description
› The TCU provide dynamic aggregation of RAN and cell site traffic streams: Ericsson GSM Abis over IP, WCDMA NodeB Iub over IP, LTE EnodeB (S1, X2), TDM from legacy RBSs through circuit emulation services (CES) and IP traffic from other equipment on the RBS site.

TCU Description
› The internal highly stable Oven Controlled Crystal Oscillator (OCXO) of the TCU maintains the frequency needed to provide the connected RBSs with accurate timing via the E1/T1 interface or Clock Output (1PPS) interface.
› During operation, the TCU automatically calibrates the OCXO using one of the following methods: - According to the E1/T1 signal at the E1/T1 interface.
- Network Time Protocol (NTP) or Precision Time Protocol (PTP over UDP and PTP over Ethernet; IEEE 1588) time server(s) accessed through the IP transport network. - According to a SynchE (Synchronous Ethernet) Master reference on an Ethernet interface.

TCU Description
› TCU provides the following to the RBS site: › 8 Gigabit Ethernet ports for aggregation of traffic from multiple digital units › 4 T1 ports on TCU which carries 2 T1s per port for connecting GSM RBS cards (DUG) › Advanced shaping functionality for up to eight queues, with large buffer depth, supporting
highest LTE capacity. › Can act as an IP router and/or as an Ethernet bridge suiting all backhaul deployment
scenarios. › Supports NTP, 1588v2 and synchronous Ethernet for RAN synchronization. › Has a local oscillator with 12 months holdover time supporting synchronization over
virtually any backhaul technology, including satellite. › Provides Ethernet LAN/WAN connectivity for local site equipment › IP over the TDM (for migration) › Supports native IP transmission (Abis IP) for Ericsson GSM RBSs making a true All IP
multi standard RBS. › OSS-RC Management System guarantees smooth operations management.
