Administering the ATM Switch
To administer the ATM switch, refer to your switch’s quick reference guide. 
Administering DEFINITY ECS
The DEFINITY ECS switch software provides 2 kinds of ATM service: 
nATM Por t Network Connectivity (ATM-PNC)

Ta b l e  3 outlines important concepts to observe when administering ATM.
ATM Port Network Connectivity (ATM-PNC) 
Each DEFINITY port network must be translated in the PPN’s screen with the full 
ATM address (The ATM switch prefix, plus the port network’s ESI, plus a Selector 
of 0) that uniquely identifies it.
Use the procedure in Ta b l e  4
 to administer ATM-PNC:
Table 3. General DEFINITY ECS ATM parameters 
Concept Description
PNC duplication If you are installing or upgrading a critical reliability system, you must enable 
the PNC duplication on the system-parameters customer-options screen (init 
password required) before the feature can be used. If it is enabled, you must 
further
nAdd pnc-a or pnc-b to command strings to clarify which carrier the ATM 
interface circuit pack is in
nSpecify the location of the ATM interface circuit pack serving as the 
duplicate
The ATM interface circuit pack in the A carrier must be in the same port 
network as the B carrier. If not, an alarm is issued. You need not administer 
ATM interface circuit packs serving as backups to each other with the same 
parameters. 
Fiber links You do not need to administer fiber links for ATM-PNC. Information on the 
ATM circuit pack screen identifies which packs are used for PNC (endpoint-
1), and endpoint-2 is administered on the ATM switch.
Remote switch 
administrationA remote switch connected with a permanent virtual circuit (PVC). The 
DEFINITY system recognizes the remote switch as a node with compatible 
circuit parameters at the other end of an emulated circuit.
You can connect a remote switch to the DEFINITY with one or more CES-
emulated circuits.  In such a case, the emulated circuits remain discrete.
Synchronization PNC—All synchronization is derived from the ATM switch providing port 
connectivity. The ATM switch obtains synchronization from either a sync 
splitter attached to one or two DS1 cards or from the ATM network.
CES—Synchronization is derived the same way it is in a non-ATM-PNC or 
ATM-PNC environment, whichever applies.

— as an ATM-CES direct connect
— through an ATM network using PVCs
Both p roc ed ures are in Ta b l e  9
, und er  “ATM-CES administration 
p roc ed ure” on page 223.
nUses ATM emulated circuits instead of physical T1/E1 tie-trunks out to the 
ATM network.
nUses up to 8 signaling groups per TN2305/TN2306 to create virtual 
trunking.
nUses bearer (B) and signaling (D) channels, similar to ISDN facilities but 
does not support nonfacility associated signaling (NFAS).
nUses channels inside each signaling group, which appear as if they were 
ports on the TN2305/TN2306 circuit pack. Hereafter, these are referred to 
as ports.
nUses constant bit-rate (CBR) signalling over permanent virtual connections 
(PVCs).
nHas a transparent DEFINITY feature set to other locations through 
narrowband QSIG (N-QSIG) or distributed communications system over 
ISDN-PRI (DCS+)
NOTE:
Bec ause ATM trunks always ap p ear as ISDN-emulated  trunks, they

nThe TN2305/TN2306 ATM Interfaces must be used with ATM CES, with 
ATM WAN PNC, and if multiple ATM switches are used.

The maximum number of emulated circuits 
(signaling groups) on a single TN2305 circuit 
pack is 8.A circuit pack can have more than one 
signaling group and more than one D-channel. 
The D-channel from one emulated circuit 
cannot signal for the bearer channels of 
another emulated circuit (no NFAS for virtual 
circuits).
A minimum of 7 ports must be administered for 
each emulated circuit (signaling group).Because this includes the D-channel, at least 6 
B-channels and the D channel must be 
administered in a signaling group.

The D channel is automatically populated in

The TN2305/TN2306 circuit packs provide up to 
248 ports for trunking.A circuit pack has 256 ports, but ports 1 
through 8 are reserved for future use. Of the 
248 available ports, 8 are for D-channels, and 
240 are for B-channels.

Trunk groups 
At least one trunk group is typically created for each remote switch with these 
attributes (see Screen 9
):
nGroup Type 
field is isdn
nCarrier medium 
field is atm
nDial Access? field is always n
nTN2305/TN2306 may have Trunk Access Codes (TAC), but these are for 
repor ting purposes only and cannot be dialed.
nCDR records for ATM trunk calls are maintained. 
NOTE:
Release 7 introd uc ed  3-d ig it p ort numb ers for ad ministering a CES 
trunk, and  CMS c annot read  the old 2-d ig it numb ers. Release 8 CMS 
software c an read  both the 2- and  3-d igit p ort numb ers.
nA trunk group may include ports from more than one of the ATM circuit 
packs in the system.  This enables 
same module preference, the feature 
that gives preference to outgoing trunks on the same port network as the 
originator.
nATM trunk groups can only contain ports on ATM boards, and ports on ATM 
boards cannot be assigned to non-ATM trunk groups.
ATM-CES trunk board
When administered as a trunk board, the TN2305/TN2306 can have up to 8 ATM 
signaling groups with up to 30 members per signaling group over an OC-3/STM-1 
connection. Although the ATM board does not have physical ports, software

makes the ATM board appear as if it does. This concept is depicted in Figure 3-1. 
Multiple TN2305/TN2306 circuit packs in a port network could connect to different 
AT M  s w i t c h e s .
Figure 15. DEFINITY signaling groups and members for ATM trunking
nEach of the 248 ports in the ATM trunk group are either B-channels or  D-
channels.
nEach B-channel has an associated maintenance object with a very simple 
maintenance strategy. This is done so that any of the virtual ports on a 
single ATM interface circuit pack can be members of different trunk groups. 
When a trunk group is busied out, only those por ts in that trunk group are 
taken out of service. Because all ports associated with a single D-channel 
follow the same PVC, you cannot test them individually.
