MINI-LINK SP 110 is a Cost efficient and Compact Mobile Backhaul Gateway that focuses on aggregating Ethernet and TDM traffic from multiple generation RBS’s. It can be used both in an optical packet network and in a microwave network where it is a perfect indoor unit for the outdoor packet radio MINI-LINK PT.Ericsson’s cost efficient Multi Access Aggregation Node
RBS interface and demarcation point
As a Mobile Backhaul Gateway MINI-LINK SP 110 is located at the edge of the Mobile transport network interfacing directly to the Radio Base Stations. It provides backhaul transmission for existing and future bandwidth demanding mobile broadband services.
MINI-LINK SP 110 provides E1 emulation at the backhaul interface for 2G networks and Fast Ethernet/ Gigabit Ethernet for 3G/ 4G backhaul. It also provides multiple sync input/output options for maximum synchronization solution flexibility. The backhaul service is supported by MEF-defined Ethernet virtual connections: point-to-point E-Line and ultipoint-tomultipoint E-LAN services. As a circuit emulation gateway,
MINI-LINK SP 110 incorporates the latest CESoPSN and SAToP standards. When acting as a demarcation device, MINI-LINK SP 110 supports the expected UNI functionality as well as Ethernet Service OAM. The device enables the separation of different network segments as well as different business responsibility areas.
MINI-LINk SP 110 is a Cost efficient end node or small hub in optical networks.
It is easy to install and configure. It aggregates Ethernet traffic from local sites with 8 Gbps full duplex, non-blocking, switching capacity. TDM traffic is handled by use of Circuit emulation, and Traffic protection can be done by use of e.g. LAG, ERP or RSTP/MSTP. E2e management is done with ServiceOn, a common management system for all Ericsson transmission products.
Ethernet Service OAM is available for error-tracing and supervision. MINI-LINK SP supports multi-vendor environment MINI-LINk SP is the compact indoor unit for the outdoor packet microwave terminal MINI-LINk PT.
The combination offers a number of carrier grade functions; up to 1 Gbps microwave capacity per link, Multiple Ethernet ports, aggregation of traffic from south-bound and local sites, local access to DCN without disturbing traffic, TDM support via Circuit Emulation Services and Ethernet Service OAM. Up to four MINI-LINK PT radios can be used per MINI-LINK SP 110.Ethernet switching
The integrated non blocking Gigabit Ethernet switch (IEEE 802.1Q and 802.1ad compliant) has a switching capacity of 8 Gbps Full duplex, 16 Gbps Half duplex.
MINI-LINK SP 110 offers multiple protection options like LAG (802.1AX Link Aggregation),
Ethernet Ring Protection (ITU G.8032v2) and RSTP/MSTP.
Quality of Service
Service differentiation (802.1 p-bits) and traffic separation (VLAN) together with 8 priority queues and traffic scheduling makes MINI-LINK SP 110 prepared for diverse QoS configurations.
The QoS is Ethernet, IP and MPLS aware. MINI-LINK SP 110 provides Carrier Grade QoS functions like SPQ, WFQ, WRED and Policing. Both ingress and egress Policing are available for configuring Service Levels that enable network carriers to provide end-to-end guaranteed bandwidth and service level agreements.
Connection-oriented logical flows can be established with MEF 10.1 defined Service Attributes: Committed Information Rate (CIR), Committed Burst Size (CBS), Excess Information Rate (EIR), and Excess Burst Rate (EBS). The attributes are configurable per flow.
Virtual LAN (VLAN)
MINI-LINK SP 110 supports VLAN tagging (IEEE
802.1Q) and Provider Bridge (802.1ad).
As part of end-to-end network solutions, MINI-LINK SP 110 complies to Link OAM (IEEE
802.3ah) and Ethernet OAM (IEEE802.1ag); together with Ethernet PM (ITU-T Y.1731).
Circuit Emulation Service
MINI-LINK SP 110 provides circuit emulation services for legacy E1 TDM interfaces. The SAToP (Structure Agnostic TDM over Packet) emulation method disregards any structure that may be imposed on the data stream; e.g. the standard framing as defined in ITU-T G.704.
The emulation endpoints do not interpret the TDM structure nor participate in the TDM signaling. The CESoPSN (Circuit Emulation Service over Packet Switched Network) emulation is a structure aware Pseudowire encapsulation method.
The ITU-TG.704 TDM structure can be identified, and recreated at the remote end. MINI-LINK SP 110 is hence well equipped to cater for the needs of different network technologies and CES head-end requirements.
MINI-LINK SP 110 has a comprehensive range of synchronization possibilities. This makes it prepared for a variety of synchronization scenarios. The Gateway allows different clock sources:
- Synchronous Ethernet, (ITU-T G.8261/G.8262/G.8264)
- Precision Time Protocol, PTP, (IEEE 1588v2 client)
- Adaptive clock recovery based on the RTP packet stream from the Packet Switched Network (PSN).
- E1 Line clock
- Local clock MINI-LINK SP 110 furthermore provides a separate 2 MHz clock input and output sync port, as well as a sync port dedicated for TDD base station sync requirements, such as Time Of Day (TOD) and 1pps input.
The alarm interface of the MINI-LINK SP 110 provides four user inputs together with two user outputs.
Management is handled by ServiceOn EM. Local management can be performed by either using the Local Craft Tool (LCT) or a Command Line Interface (CLI).
MINI-LINK SP 110 comes with a front-mounted fan unit. The fan unit can be replaced without traffic interruption.
Power is supplied by -48 VDC through dual fuse protected power inlets.
MINI-LINK SP 110 is ready for wall-mounting or installation in 19”/ETSI racks.
