Capacity and Coverage optimization59) RBS600 supports: GSM, WCDMA, LTE and WIFI60) TCU-02/SIU-02Transport sharing for RBS 6000 The TCU 02 (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.The TCU 02 has the same form-factor as a digital unit and shall be placed in the radio shelf of the RBS. It is available in product packages for all RBS 6000 cabinets. In addition to the transport functionality of the digital unit the TCU adds the following capabilities to the RBS: 8 Gigabit Ethernet ports for aggregation of traffic from multiple digital units 8 E1/T1 ports for connecting GSM RBS cards (DUG) IP over the TDM (E1/T1) backhaul (as a solution during migration) 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. Supports native IP transmission (Abis IP) for Ericsson GSM RBSs making a true All IP multi standard RBS. Provides Ethernet LAN/WAN connectivity for local site equipment Transport sharing for RBS 2000/3000 The SIU 02 (Site Integration Unit) is the 19 inch sibling to the TCU 02. It is designed to fit into the transmission space of the RBS 2000 or 3000, or alternatively in any 19 inch standard indoor rack. It supports the same features as the TCU 02 but has the following hardware differences.16 E1/T1 ports allowing for more GSM RBS to be connected to the SIU Inbuilt fan unit needed for forced cooling.61)The NSB Silver (NSB FT series) battery is for customers in a stable power grid with few outages over a longer period of time. Focus is on a long lifetime therefore minimizing site visits, replacement and costs.The Premium battery (OPzV) is a more expensive battery designed to withstand frequent outages and in applications with stable mains and have a long float life. The High Capacity battery (EON) is developed for a fast recharge therefore recovering very fast. This is necessary for Lead acid battery to survive. A standard battery takes about 24 hours to recharge while High Capacity is capable to recharge within 8 hours. EON is the choice for unstable grids due to its high charge acceptance, float life and high capacity. It is also applicable in long float life conditions, i.e. stable power grid environments.The High Cyclic battery (NSB Blue) is developed for a fast recharge and therefore works excellent where mains interruptions are frequent. For markets with many outages a day or unpredictable power sources like wind, sun etc this is the battery to use. The Blue battery can unlike any other lead acid battery run on Partial State of Charge [PSOC]. This means that the battery will not suffer from deterioration when the required recharge time is unavailable. This also makes the battery unparalleled for Hybrid operation.When it comes to batteries in high-cyclic operation, the battery capacity is not as crucial as for stand by operation. Batteries in high-cyclic operation shall be dimensioned by optimizing the charge/discharge window. The best high-cyclic performance will be reached when the batteries doesnt have to be fully recharged. Charging of the batteries between 80-100% usually takes up to 50% of the charging time.In hybrid operation a charge/ discharge window between 60-80% State of Charge, will be the most energy and cost efficient solution. A more frequent cycling using a narrow charge/discharge window of the battery capacity will most likely give a more energy effective solution than a few more deeper discharge.
