E1 Digital Trunk Requirements for Cisco Unified MeetingPlace Systems

E1 Digital Trunk Requirements for Cisco Unified MeetingPlace Systems

Confirm that the E1 digital trunk specifications meet the requirements in Table 1-6.

Table 1-6 E1 Digital Trunk Requirements

Country

Requirements

 

 

European Union

Connection Type—Euro ISDN and QSIG digital telephony (E1).

 

Cable supplied by Cisco Systems—25-foot Cat5 cable with RJ-48c connectors at

 

each end.

 

Socket—Connector must be an RJ-25 socket or an NBNC (female) connector.

 

Cable length (if you provide your own cable)—Maximum cable length is 328 feet.

 

 

Australia

Cisco Systems does not supply any E1 cables with Cisco Unified MeetingPlace

 

Audio Server systems that are shipped to Australia.

 

 

In some cases, the RJ-48c cables that Cisco Systems provides may not be appropriate for your PBX or NIU-side connections. If this is the case, create your own custom cables. Custom E1 and T1 PRI cables require the following:

Cat5e UTP cable.

RJ-48c connector on the breakout box side.

Add the ferrite that is on the cable that is supplied by Cisco Systems.

Note In E1 Cisco Unified MeetingPlace systems, you can connect Cisco Unified MeetingPlace directly to the PSTN. You do not need a CSU.

E1-Supported Protocols for Cisco Unified MeetingPlace Systems

The following protocols are supported for E1 digital trunks:

Euro-ISDN (ETSI 300-102).

QSIG (ECMA version)—Channels are numbered 1 to 30.

QSIG (ETSI version)—Channels are numbered 1 to 15 and 17 to 31.

The Cisco Unified MeetingPlace system supports only E1 PRI protocols. The Cisco Unified

MeetingPlace system does not support E1 CAS protocols.
