MCG 3100 network deployment 15

The BES defines the data networking requirements between the

BlackBerry device and the BES. The BES configuration must include

the BlackBerry Mobile Data System (MDS) to allow the MCC 3100 for

BlackBerry to route HTTP traffic to the BES, and then to the Enterprise

MCG 3100.

When you deploy the MCG 3100, data originates from the BES for the

MCC 3100 for BlackBerry clients. The BES infastructure controls the

boundary between the untrusted and trusted network, making the overall

deployment less complex.

BlackBerry (without BES), Nokia, and Windows Mobile deployment

considerations

The MCG 3100 uses HTTPS over the cellular data network. The

MCG 3100 must be deployed so that internet traffic can reach it at the

same time that it communicates with the ECS TLAN.

To deploy the MCC 3100 for BlackBerry (without the BES), MCC 3100

for Nokia, and MCC 3100 for Windows Mobile, determine how to forward

the HTTPS traffic from the public internet (untrusted) to the Enterprise IP

network where the MCG 3100 resides. Certificates to support HTTPS on

the devices must be deployed. The certificates require the MCG 3100

Fully Qualified Domain Name (FQDN). The FQDN must resolve on both

the cell data network (internet) and on any wireless network used by the

devices to communicate with the MCG 3100.

If desired, you can use wireless access in place of cell data access

(internet) for HTTPS signaling with the MCG 3100. In this deployment, the

clients have IP access to the MCG 3100 after becoming associated with

the wireless network.

Network bandwidth requirements

Use the following sections to calculate the network bandwidth

requirements for the MCG 3100.

• "HTTP Signaling" (page 16)

• "SIP signaling bandwidth requirements" (page 16)

• "RTP media bandwidth requirements" (page 16)

Based on the assumptions in these sections, the MCG 3100 supports

1500 users per gateway with a maximum of 350 simultaneous calls on a

100BaseT network.
