Cisco Cisco Unified MeetingPlace Audio Server Installation Guide

•

In some cases, the cables provided are not appropriate for the customer’s 
PBX or NIU side connections. In this case, customers can create custom 
cables. Custom E1 and T1 PRI cables require:

•

Cat5e STP UTP cable

•

Add the ferrite that came on the Cisco-shipped cable

•

RJ-48c connector on the breakout side box

•

In E1 environments, MeetingPlace can be tied directly to the PSTN, and 
no CSU is needed.

The following illustrations show examples of different configurations and 
their resulting system capacities.

E1 Multi Access Blades are installed starting at the bottom-most card 

slot (slot 1 in the following illustrations) and proceed toward the top, 
immediately followed by Smart Blades, if needed. IP Multi Access Blades are 
installed starting at the top-most card slot (slot 6 in the following illustrations) 
and proceed toward the bottom.

The following illustration shows a pure E1 configuration: 960 PSTN ports, 
960 total ports. In the example, MA=Multi Access Blade. SB=Smart Blade.

The following illustration shows a pure IP configuration: 960 IP ports, 960 
total ports. In the example, SB=Smart Blade (no E1 functionality). MA=IP 
Multi Access Blade. Smart Blades can support up to 48 ports of E1 PRI or 
VoIP. IP Access Blades and Multi Access Blades both require associated 
Smart Blades.
