Customer Enterprise Network Components
The network components that are provided by the customer are defined in this section. The following
components reside within the Customer Enterprise Network (CEN):
• Domain Name Services (DNS) Server
• Dynamic Host Configuration Protocol (DHCP) Server
• Virtual Private Network (VPN) Server
DNS Server
The Domain Name Services (DNS) server contains a database of network hostnames and their
associated IP addresses for Intranet resources connected to the Intranet. The DNS server contains
entries for the ASTRO Radio Network Infrastructure (RNI) devices (PRX 7000 Console Proxy, ELAM
Server, KMF, etc…).
DHCP Server
The Dynamic Host Configuration Protocol (DHCP) server assigns an IP address to a computer from a
defined range of numbers configured for a given network. Each MCC 7100 IP Dispatch Console that is
remote from the ASTRO RNI will be assigned a static IP address in the DHCP Server.
VPN Server
The VPN server allows for virtual private network (VPN) connections by an MCC 7100 IP Dispatch
Console deployed outside the CEN. The MCC 7100 IP Dispatch Console connects to the CEN over the
Internet. This provides individual dispatch operators with secure access to the CEN and ultimately to
the ASTRO RNI.
MCC 7100 IP Dispatch Console Theory of Operations
This section describes the functional relationships between components that support the MCC 7100 IP
Dispatch Console.
Zone Database Server and LDAP
The MCC 7100 IP Dispatch Console uses Lightweight Directory Access Protocol (LDAP). The Dynamic
Host Configuration Protocol (DHCP) server assigns an IP address to a computer from a defined range
of IP address numbers configured for a given network. Each MCC 7100 IP Dispatch Console outside
the ASTRO
®
25 Radio Network Infrastructure (RNI) is assigned a static address in the DHCP Server.
MCC 7100 IP Dispatch Console Encryption
The MCC 7100 IP Dispatch Console supports secure encryption. See Load Secure Keys and
Algorithms on page 55 for a complete description on encryption.
MCC 7100 IP Dispatch Console Link Op
The first dispatch console at a console site that registers with the system and assigns a resource is
known as the Link Op. The Link Op refers to the console that is in control of the active link between the
site and the zone controller or site controller.
A Link Op is required at a site that contains a PRX 7000 Console Proxy so that an MCC 7100 IP
Dispatch Console outside the ASTRO
®
25 Radio Network Infrastructure (RNI) can operate. Every site,
including remote console sites, require a Link Op inside the ASTRO
®
25 RNI to operate. An MCC 7100
IP Dispatch Console outside the ASTRO
®
25 RNI cannot become a Link Op.
