Cisco Cisco Unified MeetingPlace Audio Server Installation Guide

In some cases, the cables provided may not be appropriate for the customer’s 
PBX or NIU side connections. In this case, customers can create their own 
custom cables. Custom T1 CAS and IP cables require:

•

Cat5e STP UTP cable, with shielded RJ-45 connectors terminated to the 
cable shielded at both ends

•

Add the ferrite that came on the Cisco-shipped cable

The FCC Part 68 registration number is EMC USA-34550-XD-T. Be 

sure to use only FCC and CSA- or UL-listed channel service units (CSUs).

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

PSTN cards are installed starting from the bottom-most slot (slot 1 in 

the following illustrations) and proceed toward the top, immediately followed 
by a Smart Blade, if needed. IP MA cards are installed starting from the top-
most slot (slot 6 in the following illustrations), and proceed toward the 
bottom.

Mixing protocols is not supported except in combination with 

IP ports. For example, a system cannot have both T1 and E1 ports configured 
but it can have T1 (either PRI or CAS) and IP ports or E1 and IP ports. Also, a 
system cannot have both T1 CAS and T1 PRI ports configured.

• T1 connection into PBX with INS1500-to-T1 converter.

• Cisco-supplied 15-meter shielded cable (male-male)



one per T1 span. Customer 

provides RJ-45 connector.

Cisco does not supply T1 cables with servers shipped to Australia.
