Capabilities (2/2)


There are 4 types of frames:

Control Frame (CF) always present, named CF-00 Extension Frame (EF) optional, up to 5 (from EF-00 to EF-04)Miscellaneous Frame (MF)General Purpose Frame (GPF)

CF & EF may contain up to 3 shelves

Frames & Shelves (1/8)


Control Frame (CF-00):

1st shelf is always equipped: it is the Control Shelf (CS)2nd and 3rd shelves are optional as Extension Shelves (ES)

Extension Frames (EF-00 to EF-04):

They contain Extension Shelves (ES), up to 3EF-04 can only have 1 ES

Shelf/card numbering:

they are always composed by 4 chars:

1st number is frame (1=CF-00, 2=EF-00, 3=EF-01...)2nd number is shelf (1=top, 2=middle, 3=bottom)3rd/4th numbers are shelf or card (00=shelf, 01=1st card from left, 02=2nd card from left, etc. - Up to 18 cards)

E.g.: 1203 = CF-00, middle shelf, 3rd board (from left)

Boards xx09 and xx10 are smaller and lay in the same slot, xx09 on top of xx10

Frames & Shelves (8/8) - NumberingCards can exist in 3 different formats:

Double Slot cards mustalways be configured in ODDlocations

E.g.: 1103 card fits into1103 and 1104 locations, itcannot be configured ontolocation 1104

Double Slot (they fit in 2 consecutive slot locations)

Single Slot (they fit in a single slot location)

IMT BUS cards (2 cards fit in 1 single slot location)


It contains the Maintenance & Administration Subsystem (MAS) modules, in fixed slots.

MAS is composed by two MAS Processors (MASP A & B), and one Maintenance Disk & Alarm Card (MDAL).

Each MASP is composed by:

General Purpose Service Module (GPSM-II) card in slot 1113 (forMASP A) and 1115 (for MASP B)

Terminal Disk Module (TDM) in slot 1114 (for MASP A) and 1116 (for MASP BB)

MDAL is a double slot card located in slots 1117 & 1118. It is a single card, not duplicated.

Other slots (except 1109 and 1110) are for application cards

Slots xx09 and xx10, for all the shelves, are reserved for High Speed Multiplexer Cards (HMUX). These cards provide two buses(IMT) to interconnect all the shelves



16 MMI (Man Machine Interface) ports for terminal interfaces

2 ports for external timing (synchronization)

2 ports for each possible application card

4 IMT ports

Power distribution


Each frame has a FAP on top. Each FAP is composed by:

2 Diode Boards that provide two power buses to the frame1 Jumper Board that takes care of a power bus when one power source is unavailable (in this case power is taken by the othersource)

EAGLE STP has 3 subsystems:

Maintenance & Administration (MAS)

Communication

Application

Subsystems


MAS is MASP A + MASP B + MDAL

MASP is GPSM-II + TDM

In short:

GPSM-II is the processorTDM is the diskMDAL is the backup unit (via magnetic-optical disk)

Maintenance & Administration Subsystem (1/2)


During boot, data is transferred from TDM to GPSM-II and then to allthe application cards via IMT buses.

Maintenance & Administration Subsystem (2/2)

After that, MAS subsystem crashes are no traffic affecting


Each GPSM-II is connected to its own TDM via a SCSI ExtendedBus Interface (EBI)

GPSM-II is the board that connects MAS with CommunicationSubsystem (IMT buses)

GPSM-II collects measurements & alarm reports

TDMs are connected each other and to MDAL via SCSI bus

Removable disk data storageAlarm processing

If MDAL is removed no audible/visible alarm is reported

Single card shared by both MASPs

Removable disk data storage

Uses 2.3 gigabytes two-sided, removable disk

Only side A is supported

Insert with disk side A facing right

MDAL


Provides Interprocessors Message Transport (IMT) buses.

There are 2 IMT buses, composed by 2 cards in every shelf, positions xx09 and xx10.

All cards in slots xx09 belong to BUS A.

All cards in slots xx10 belong to BUS B.

If both IMT buses are broken, total outage

Intershelf IMT capacity: 1Gbps

Shelf ring capacity (max 16 shelf rings): 125 Mbps

Shelf ring capacity with HIPR (new HMUX High-speed IMT PacketRouter): 1 Gbps

Communication Subsystem (1/2)


Communication Subsystem (2/2)


Composed by Link Interface Modules (LIMs) and Memory(Database) Modules

LIMs are ATM, E1, T1, etc.Memory Modules contain database (e.g. GTT data, GWS data, etc.)

Application Subsystem


With HC-MIM, HIPR is required

EAGLE capacity is max. 1500 links (*)

Link Interface Module (1/2)LIM: up to 2 signaling links

MIM(Multichannel LIM): up to 8 signaling links

This is the evolved TSM and supports VSCCP application, that is GTT and GWS plus:

G-Port: GSM portable numbering planG-Flex: GSM flexible numbering planEIR: Equipment Identity RegisterINP: INAP based number portabilityLNP

Database Services Module (DSM) (1/2)


Up to 4GB memory available for data (4 banks of 1 GB)Capable of 1700 GTT per second if only GTT function is performed. With other functions: 850 GTT/s

Max 25 DSM cards per EAGLE (*)

Database Services Module (DSM) (2/2)

Note:

more cards means more speed and not more capacity,

as the database is replicated in every card



E5-SM4G

The E5-SM4G is a Database Service Module (DSM) designed to operate at high capacity. The E5-SM4G is a double-slot EAGLE card that provides 3.1 GB of application processor memory.

The E5-SM4G provides the following for the EAGLE system:

Support for the VSCCP features

Can interoperate with DSMs at an operating capacity of 1700 transactions

per second (TPS).

Support for the 150K TPS GTT and 75K TPS G-Port features

Can replace a DSM in the control or extension frame without requiring additional provisioning.

Transport Adaptation Layer Interface (TALI) and SigTranIPLIMI functionality: one-to-one, provides max. 8 links to IP network

IPGWI functionality: one-to many (max. 50 points)

Database Communication Module (DCM) (1/2)


IPLIMI: adaptation layer is M2PA for SS7 A, B, C, D, E linksIPGWI: adaptation layers are M3UA and SUA for SS7 A, E links. That is, IPGWI cannot connect an STP

EAGLE supports max. 100 IPLIMIs and max. 64 IPGWIs (*)

E5-ENET (1/2)

The E5-ENET card is a single slot card providing one or more Ethernet interfaces. The E5-ENET card has the following requirements and dependencies:

The E5-ENET has 2 physical 10/100 Mbps Ethernet ports. The E5-ENET supports protocols as identified below:

For IPLIMI application: SCTP, M2PA

For IPGWI application: SCTP, M3UA, SUA

NOTE: The E5-ENET is provisionable for IPLIMx or IPGWx, but does not support both functions on a single card simultaneously.

Users Administration

In Vodafone network, eagle user must not be usedPersonal usernames are presentEvery single user has been given access rights to different command classes. For example, rtrv-secu-user:USER ID AGE PAGE UOUT REV LINK SA SYS PU DB DBGUser1 362 0 0 NO YES YES YES YES YES YESUSER ID AGE PAGE UOUT REV LINK SA SYS PU DB DBGUser2 362 0 0 NO NO NO YES NO YES NO


Commands are composed by Keywords and Parameters.

Command syntax (1/2)

Keywords

Identify the principal action to be performed by the system

Consist of one to three words, separated by a hyphen delimiter

Keywords examples:

login

chg-trm

rept-stat-db


Commands are composed by Keywords and Parameters.

Command syntax (2/2)

Parameters

Further define the command operation

Colon separates keyword from parameter

Colon is also the delimiter between parameters

Mandatory or optional

Complete command (Keyword+parameters) examples:

login:uid=eagle

chg-trm:trm=20:all=yes

rept-stat-db:display=all


A route is the definition of how to reach a point code via a linkset, with an associated cost

It is possible to configure max. 5000 routes (*)Max number of routes towards a destination is 6 (*)It is possible to associate a cost to each route: if the cost is the same for each route, theres load sharing, otherwise there are preferential routes. In this case, other routes are involved only if theres congestion on preferential routes

SS7 Provisioning - Notes



Active and standby disks (TDM) are mirrored via SCSI bus. Each disk contains:
