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 .
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.
Figure 1-3 illustrates the Cisco Unified MeetingPlace digital telephony connections with E1 trunks.
