The ME Identity is checked by the MME passing it to an Equipment Identity Register (EIR) and then the MME
analyzes the response from the EIR in order to determine its subsequent actions; like rejecting/attaching a UE.
Multiple PDN Support
It provides multiple PDN connectivity support for UE initiated service request.
The MME supports an UE-initiated connectivity establishment to separate PDN GWs or single PDN GW in order to

Management System Overview
The system's management capabilities are designed around the Telecommunications Management Network (TMN)
model for management - focusing on providing superior quality network element (NE) and element management system
(Web Element Manager) functions. The system provides element management applications that can easily be integrated,
using standards-based protocols (CORBA and SNMPv1, v2), into higher-level management systems - giving wireless
operators the ability to integrate the system into their overall network, service, and business management systems. In
addition, all management is performed out-of-band for security and to maintain system performance.
Operation and Maintenance module of ASR 5000 offers comprehensive management capabilities to the operators and
enables them to operate the system more efficiently. There are multiple ways to manage the system either locally or
remotely using its out-of-band management interfaces.
These include:
Using the command line interface (CLI)
Remote login using Telnet, and Secure Shell (SSH) access to CLI through SPIO card's Ethernet management
interfaces
Local login through the Console port on SPIO card using an RS-232 serial connection
Using the Web Element Manager application
Supports communications through 10 Base-T, 100 Base-TX, 1000 Base-TX, or 1000
Base-SX (optical gigabit Ethernet) Ethernet management interfaces on the SPIO
