RPC/RP Manual 19June2000 WLL-RPC/RP-IN/UM-1.0 iiiImportant Safety Instructions ! Safety Information: Installer and User WARNING The device is to be installed and operated at a “fixed location”. The term "fixed location" means that the device is physically secured at one location and is not able to be easily moved to another location. It must be located - (for indoor RPs) up on or near the ceiling away from users or bystanders – (for outdoor RPs) on the roof top site, pole, building, or traffic light away from users or bystanders. It must be mounted in a manner to ensure that a minimum separation distance of 20cm is normally maintained between all users, bystanders and the antenna (including any radiating structure). The installer may be required to perform an MPE evaluation and an Environmental Assessment (EA) of the location at the time of licensing per CFR 47 Part 1.1307. Fixed mounted antennae that are co-located with other antennae must satisfy the co-location requirements of Part 1.1307. Limits: The limit for general population/uncontrolled environment exposures is 1 2/cmmW for the band 1895-1910 MHz. MPE evaluation: The following calculations are provided for the more restrictive limit: uncontrolled environment/general population. The calculated minimum safe distance, Radii(cm), is approximately 10 times lower than the minimum required installation distance of 20 cm per Part 2.1091.
RPC/RP Manual WLL-RPC/RP-IN/UM-1.0 19June2000 iv Therefore, the transmitter model numbers EA7H74B and EA7H75B complies with the MPE requirements by providing a safe separation distance between the antenna (including any radiating structure) and any persons.

19June2000 WLL-RPC/RP-IN/UM-1.0 2 RPC Installation 2 RPC Installation 2.1 General Description The Radio Port Controller (RPC) functions as the controller and power distributor for the Radio Ports (RPs). It is also the concentrator of the speech paths and the protocol converter for the PHS protocol and the Q.931 protocol. It has Dual Tone Multi Frequency (DTMF) senders for dialing to the Local Exchange (LE) through the Central Office Terminal (COT). In addition, the RPC synchronizes the associated RPs by extracting the synchronous clock from the E1 line connected to the COT and distributing it to all of the associated RPs. RPCs can be co-located with a COT or located remotely and communicate with the COT using E1 transmission over: • High Density Subscriber Loop (HDSL) • Fiber Optic Transmission (FOT) • Digital microwave radio Figure 2-1 presents an overview of the RPC and RPs in the WLL system.
RPC Installation RPC/RP Manual WLL-RPC/RP-IN/UM-1.0 19June2000 2-2 Figure 2-1: RPC in the WLL System 2.1.1 Main RPC Features An RPC consists mainly of four types of function modules: • One ECNT (Enhanced Control) module • Up to four E1IF (E1 Interface) modules • Up to eight RPIF (RP Interface) modules • One APL (Application Software Loading) module - Optional Figure 2-2 displays the four types of the function modules in the RPC.
RPC/RP Manual RPC Installation 19June2000 WLL-RPC/RP-IN/UM-1.0 2-3 Figure 2-2: Function Modules inside the RPC Each RPC can handle traffic loads of up to 120 simultaneous telephone calls. Four E1 trunks connect to the COT side and support 30 subscriber channels each. In normal traffic conditions, a single RPC can service approximately 1000 subscribers. The RPC is monitored and controlled from the network management system connected to the COT. With this setup the program data, the operation data, and the system parameters can be changed and the alarm information and traffic data can be gathered easily. 2.1.2 RPC Module Descriptions The following sections describe the RPC component modules, including the physical configuration, Light Emitting Diodes (LEDs), and switch operations.
RPC Installation RPC/RP Manual WLL-RPC/RP-IN/UM-1.0 19June2000 2-42.1.2.1 Enhanced Control Module The ECNT module provides the Operation, Administration and Maintenance (OA&M) support for the RPC. In addition, it provides the time slot cross connect switch for communications between the E1IFs and the RPIFs. Figure 2-3 represents the ECNT functions. Figure 2-3: ECNT Block Diagram The ECNT module performs the clock synchronization by generating a synchronized clock from the extracted clock signal from the E1 line on the E1 interface card and delivers it to the RP lines on the RP interface cards. The RPC uses a control bus via the ADPCM highway on the mother board to synchronize the system. The Control Bus is an 8-bit mixed bus address with data and First-in First-out (FIFO) type bus. The main CPU on the ECNT card, the local CPUs on E1 Interface cards and the RP-interface cards are all connected by this bus. The main CPU on the ECNT card controls the bus.

The E1 Interface (E1IF) module communicates externally with the COT through 1 G.703 E1 interface and uses Q.931 non-facility associated signaling protocol. Transmission between the RPC and RP is based on a proprietary, echo-canceled transmission standard, which is similar to the recognized G.961 ISDN standard. The E1IF provides the speech coding conversion between A-law PCM from the COT and Adaptive Differential Pulse Code Modulation (ADPCM), which is ITU-
RPC Installation RPC/RP Manual WLL-RPC/RP-IN/UM-1.0 19June2000 2-6Rec.726 compliant, from the RP. It supports 32 kbps channel signaling for encoded voice and voice band data calls. In addition, the E1IF communicates internally with the Radio Port Interface (RPIF) module for interfacing RPs through the backplane busses and the switch in the ECNT module. The E1IF module is an E1 module (E1M) that provides 4 E1 connections to the E1 network. The E1 module has the following functions: • Originates/terminates 4 G.703/G.704 2.048 Mbps E1 interface • Provides 75 ohm unbalanced interface • Provides LEDs for module and port status and alarms • Performs CRC-4 on the E1 line according to G.706 • Monitors performance of each E1 line • Detects errors and alarms on the E1 lines.

The RPC connects to the RPs through a 2-wire proprietary interface. Line power feeding from the RPC provides a power source of 116V DC to the RPs. The RPC controls the RPs via 8 RPIF modules. Each RPIF module provides an ISDN Basic Rate interface to 4 RPs. The RP is extended from the RPC to a maximum distance of 5.0km using a pair of φ0.5 wires and approximately 3.5 km using a pair of φ0.4 wires. The Radio Port Interface (RPIF) module communicates externally with four RPs through ISDN Basic Rate Interfaces (BRI). In addition, it communicates

19June2000 WLL-RPC/RP-IN/UM-1.0 3 RP Installation 3 RP Installation 3.1 General Description The Radio Port (RP) is the radio equipment base station that relays the communication from the user side to the operator/network side or vice versa. A standard installation for RP applications places several RPs in a common service area. However, the number of RPs and their distribution deployment depend on the following factors: • Topography of the service area • Subscriber distribution in the service area • Desired Grade of Service and traffic load. There are two types of RPs: • Outdoor - is small in size and is encased in a weather-proof cabinet. This gives it the potential for various mounting scenarios - installed on the dedicated poles, buildings, or street lamp poles. • Indoor - is also small in size and can be installed in public and semi-public locations like an office building, a shopping mall, or an underground parking lot. The power for the RP is fed from the RPC and a synchronous clock is delivered from the RPC. The radio link between the RP and the FSU, or the RP and the PS is based on RCR-STD 28 Ver.2 PHS technology, which defines frequency bands, protocol, and so on. Both the indoor and the outdoor RPs have a 2 branch built-in antenna. The architecture of the WLL system is illustrated in Figure 3-1, which is followed by a block diagram of the RP.
RP Installation RPC/RP Manual WLL-RPC/RP-IN/UM-1.0 19June2000 3-2 Figure 3-1: RP in the WLL System
RPC/RP Manual RP Installation 19June2000 WLL-RPC/RP-IN/UM-1.0 3-3 Figure 3-2: Radio Port Block Diagram 3.1.1 Traffic Handling PHS applies Time Division Multiplex Access (TDMA) and Time Division Duplex (TDD) techniques. Each individual radio link between the RP and the FSU/PS is assigned 1 time slot for a control channel (C-ch) and 3 slots for traffic channels (T-chs). In the case of a single RP, there are 4 time slots installed for radio links. One slot is the control channel for signaling and the other three are the traffic channels. The number of accommodated subscribers in that RP covering the zone calculated according to the erlang theory is as follows: • Erlang per zone (3 T-chs, GOS=5%) = 0.899 erlang • Subscribers (FSUs or PSs) (0.899÷.08) = 11 subscribers Group Control maximizes the number of channels available for traffic by allowing one control channel to control up to 8 RPs (up to 31 traffic channels), which is an efficient application for high traffic areas. One master RP can control a maximum of 7 RPs in the same area. The master RP has one control channel, and all the other channels are assigned for traffic, leaving 31 channels open for traffic. Figure 3-3 represents the group control configuration with 4 RPs in the group.
RP Installation RPC/RP Manual WLL-RPC/RP-IN/UM-1.0 19June2000 3-4 Figure 3-3: Group Control RPs In the group control mode, the number of accommodated subscribers in the group control coverage zone is calculated in accordance with the erlang theory as follows (with 4 RPs in the group): • Erlang per zone (15 T-chs, GOS=5%) = 10.663 erlang • Subscribers (FSUs or PSs) (10.663÷.08) = 132 subscribers The comparison for the number of accommodated subscribers between the group controlled RPs and the single RP is shown in Figure 3-4. F NOTE: Figure 3-4 represents the group control with 4 RPs. Each group can have a maximum of 8 RPs.
RPC/RP Manual RP Installation 19June2000 WLL-RPC/RP-IN/UM-1.0 3-5 Figure 3-4: Accommodated Subscribers per RP in Group and Non-group Control The recommended installation design for RPs is as follows: • A zone of sparse subscribers should be covered by non-group controlled RPs. • A zone of dense subscribes should be covered by group-controlled RPs. The number of accommodated subscribers is the greatest when all of the RPs connected to an RPC are configured in the group control mode. In this case (with 4 RPs in each group), the number of service zones is eight (32÷4), and the maximum number of subscribers is 1,056 (132x8). Each Group Control zone supplies 15 traffic channels. Eight zones require 120 channels (15x8) provided by 4 E1 lines with 30 channels each. 3.1.2 Cell Overlap Maximum service results are achieved when the RP coverage area is strategically installed in a Cell Overlap Capacity.
RP Installation RPC/RP Manual WLL-RPC/RP-IN/UM-1.0 19June2000 3-6 Figure 3-5: Coverage Service Area with Cell Overlap The combination of Cell Overlap and Dynamic Channel Allocation increases the flexibility and the capacity of the system. Every user has access to all channels (77x4) due to the overlapping base station topology. Cell Overlap enhances the reliability and service quality. One malfunctioning base station does not affect the performance of the system. Due to the Dynamic Channel Allocation, there is no need for frequency planning, which allows the network to meet operators current demands with the option to easily expand at a later date. 3.1.3 Air Interface Handling The radio interface has four-channel time division multiple access capability with time division duplexing (4-channel TDMA-TDD), which provides one control channel and three traffic channels for each cell station.
RPC/RP Manual RP Installation 19June2000 WLL-RPC/RP-IN/UM-1.0 3-7 Figure 3-6: Radio Channel Structure The radio frequency allocation shown in Figure 3-6 displays a typical radio channel structure when three cordless handsets are operating through a single RP. RCR STD-28 does not designate a control channel prior to the operation. Instead, it assigns the control slot to any one of the four available slots. Traffic channels are not preassigned. Channel assignment is performed by a distributed-autonomous dynamic channel assignment scheme and is an essential function of the WLL radio system. Channel assignment for new communication is selected from the available channel resources mapped in a two-dimensional frequency-time matrix renewed by the result of checking signal strength when the call is established. The RP also completes handling of the signaling process over the radio segment. Due to the separation of the traffic and control channels, traffic channels can be allocated in a distributed and autonomous manner by employing the switching TDMA mechanism. In order to maximize the benefit of carrier switching TDMA, the RP uses a system that synchronizes radio frames by superimposing synchronization data on the B interface. The result of this synchronization is an improved utilization of frequency as compared to asynchronous systems. In addition, with TDMA-TDD and the diversity of the RP transmission and reception, it is not necessary to install the multiple antenna or receiver-branch diversity mechanisms in the PS handsets to improve the data communication
RP Installation RPC/RP Manual WLL-RPC/RP-IN/UM-1.0 19June2000 3-8quality. TDMA enables the antennas to share both transmitting and receiving with the RF switches. To implement receiving diversity, the receiving units have two receiving branches, while the transmitting unit has switches for switching antennas to provide the transmission diversity. 3.2 System Construction Figure 3-7 represents the RPC and RP configuration.
