							1 El Digital Trunk ConnectivityThis chapter has a description and brief technical overview of the El digital trunk
connectivity available for Centigram Series 
G Communications Server.
El PCM Trunking OverviewThe Series 
6 Communications Server includes El digital trunk connectivity as a
standard feature. This feature facilitates Series 6 server integration with switches
which predominantly use digital trunks for connection to the telephone network and
to special service equipment such as the Series 6 server.
*.The Model 70 and Model 1201 both support only one 
El trunk, the Model 120sand the Model 640 each support up to 3 El trunks (up to the maximum 60-port
system capacity).If you need an introduction to the El Digital Trunk Connectivity feature of the
Series 6 server for overall applications information, this section is written for you. If
you need an introduction to the El Digital Trunk Connectivity Feature as a general
review before configuring it or troubleshooting it, this section is also for you.
This section briefly reviews the structure of an El frame and time slot assignment for
common channel signaling. It 
also discusses Series 6 server/El applications, El
features, functional operation, alarms, and specifications. This section is not
intended to be a comprehensive discussion of digital trunking. For more
information on digital encoding of voice signals and digital transmission, refer to the
many external resources on the subject. Also, contact Customer Training for the use
of digital transmission in Centigram equipment.
Dual El Digital Trunk MultiplexingThe standard El frame (Figure l-l) contains 256 bits divided into 32 time slots of 8
bits each. At 8,000 frames per second, the El bit rate is 2.048 Mbps. Time slot 0 in
each frame is used for framing bits and for error-checking bits. Time slots 1 through
15 carry PCM channel circuits 1 through 15, and time slots 17 through 31 carry
PCM channel circuits 16 through 30. (The PCM h
cannel circuits carry data- that
is, digitized voice signals.) Time slot 16 in the El trunk 
KM frame is reserved for
line supervision and signaling.

Common Channel Signaling (CCS)-.“Common channel signaling” refers to signaling information for a set of 
KM
channels.In the case of a digital trunk, CCS carries signaling information for
multiple PCM channels in one or more trunks. The signaling data uses time slot 16.
Currently, the Series 6 servers use one type of CCS: Signaling System 7 (also known
as CCITT C7). Typically, Series 6 servers equipped with El trunks as a standard
feature will also be equipped with the SS7 Optional Feature (refer to the SS7
Integration optional feature documentation for your system for further information).
Note:The Series 6 Server supports SS7 as the only CCS optional feature.
Channel associated signaling will be available in a future release.
VoiceMemo and E 1 -ApplicationsDigital trunk connectivity in a Series 6 server is available as a standard feature where
the system connects to the local switch through El digital trunks. A Series 6 server
module with digital connectivity has one or more Dual El digital trunk interface
cards with one or more voice service cards (DSP30 cards, 
FaxMemo cards, and so
forth).
Digital and analog trunks can coexist in the same Series 6 server. Though not
typical, such a mix could be implemented in an application where analog trunks exist
and a digital trunk is added.

							El Digital Trunk ConnectivityE 1 Connectivity FeaturesModel 
120s and Model 640 Series 6 servers can support a total capacity of 60 PCM
voice-application channels per module. Model 70 and Model 1201 Series 6 servers
can support a total capacity of 30 
KM voice application channels per module.
Note:“Port” as used elsewhere in Series 6 Communications Server
documentation, when used in the context of digital trunk
connectivity, equates directly to 
“KM channel,” “channel,” and
“circuit.”Model 
120s and Model 640 Series 6 server modules can support up to two Dual El
Digital Trunk Interface cards with two trunks per card for Series 6 server-to-network
connections (for example, for incoming-to-help line connections). Some of the
PCM circuits can be allocated for network-to-network connections (for example, for
incoming to help line connections).
“,The user can enable or disable CRC error checking on the trunks and set line coding
for the CCITT-standard HDB3 (high density bipolar 3) The system clock can be
slaved to the incoming PCM signal or can be set to synchronize with an internal 
free-running reference.
Tip:To optimize fault tolerance on your system, configure your trunks
with the voice application circuits evenly divided between each
trunk. Then, for example, in a host with four trunks, a single
trunk going out of service results in the loss of only one-fourth of
your total available circuits.
E 1 Connectivity Functional OperationFrom the standpoint of implementation, the El trunk is expected to be the primary
trunk interface to the local switch. Setup through the 
VoiceMemo Physical Resource
Configuration Manager, the Series 6 server expects the Dual El trunk interface card
to connect to an SS7 Protocol Conversion Card. The Dual El trunk interface card
handles El frame multiplexing and demultiplexing, clock extraction, and so forth.
However, because it extracts and interprets the signaling data important to call setup,
tear down and routing, the SS7 Signal Processor card must be present before call
processing can occur.
