DIGITAL TRANSPORT SERVICE (DTS)
A.
Service Description
Digital Transport Service (DTS) provides a cost effective method of delivering voice grade service
from the serving central office to a customer’s premises. DTS is provided exclusively with
OPTINET DS1 Service (1.544 Mbps) and the 24 channels may be used for the transport of lines
for termination on customer provided equipment. DTS supports Direct Inward Dialing (DID)
Service, ValueLink Premier Services or Dedicated 800 Service, and Local Exchange Business
Service, hereafter referred to as Trunks. Touch-Tone is a required feature of DTS.
B.
Regulations
1.
DTS is offered in two serving arrangements, Integrated and Non-Integrated, from central offices
where the Company has arranged facilities for such service. Flat Rate and Message Rate local
exchange services cannot be furnished on the same premises.
a.
Integrated Service is an arrangement that allows for the direct termination of digital trunks
from a digital central office to customer provided equipment. This arrangement supports
Trunk side features only. The Integrated Arrangement is comprised of three elements, 1)
Trunk Terminations, 2) OPTINET Local Distribution Channel, and 3) Digital interface
Termination.
b.
Non-Integrated Service is an arrangement that allows for the termination of PBX trunks from
an Analog or Digital central office to customer provided equipment. This arrangement
supports Trunk side and Line side features on those trunks. This arrangement is comprised
of three elements, 1) Trunk Terminations, 2) OPTINET Local Digital Distribution Channel,
and 3) Central Office Multiplexing.
2.
Serving arrangements that require a mixture of Integrated and Non-Integrated terminations are
provided as Non-Integrated Service.
3.
The rate structure for DTS requires charges for Trunk Terminations, an OPTINET Local
Distribution Channel, Company-provided DS1 Central Office Multiplexing or Digital Interface
Termination (as required) and End User Common Line Charges (EUCL).

Availability and functionality of DTS may vary by serving central office and switch type. The
Company will determine when Integrated or Non-Integrated terminations are required and
whether DTS can be provisioned with the customer’s service and equipment.
7.
If changes in central office technology permit the Company to convert customer’s
Non-Integrated Termination to an Integrated Termination, the customer’s rate will be adjusted
to reflect the Integrated Termination rates.

Intercom
Provides up to six single digit codes by which two telephones in the same MVP may
communicate with each other. To access the intercom, the telephone user dials an access
code, followed by a single digit. Each code is associated with one of the exchange access
lines on a fixed basis; therefore, multiple stations on the same exchange access line cannot
access each other via the intercom feature. Intercom is limited to a maximum of three
simultaneous calls.

PACKET SWITCHED NETWORK (PSN) SERVICES – ISDN X.25 and Dedicated X.75
Effective July 16, 2005, no further installations, moves, rearrangements, or changes of any type will
be made to ISDN X.25 or Dedicated X.75 Packet Services. Customers of record on July 16, 2005
may continue their service as long as such service remains at the location at which it was being
furnished on the aforementioned date. In the event that these services are discontinued at their
present location for any reason, they will not be reestablished. The preceding supersedes all of the
rules and regulations that follow.
A.
Description
The Packet Switched Network (PSN) combines packet switching technology and digital
transmission facilities to provide a switched data carriage service. The PSN is designed to
provide economical, usage-sensitive data transmission for a variety of interactive (or bursty) data
applications. The PSN provides for the simultaneous two-way transmission of data at speeds up
to 64 kilobits per second (Kbps). Customers can choose between the ISDN X.25 access
arrangement which permits PSN switching to any PSN switch in the LATA and the Dedicated
X.75 Access arrangement whose PSN switching is limited to a single ISDN switch in a LATA.
Access to the Packet Switch Network is limited to ISDN Access with X.25 protocol or Dedicated
Access with X.75 protocol.
With packet switching technology, data streams are packetized and then moved through the
network to their destinations. The packet network examines, routes, and transports packets
individually without maintaining a physical path between bursts of data. In this way, greater
volumes can be transported through shared network transmission facilities and individual data
packets can be sent on alternate routes as the need arises, resulting in better system
performance and higher network availability. The reduction in network facilities results in a more
economical form of data transmission for interactive applications.
The PSN will support communications between data terminal equipment (DTE) with like
protocols.

PSN Elements
Exchange Terminations
Exchange Terminations are determined by type of facility used to access the PSN. The
exchange termination provides Data Service Unit/Channel Service Unit (DSU/CSU) function for
digital access lines.
Port Terminations
Port Terminations provide the communications interface for users accessing the PSN. They are
protocol and speed specific. A NTN is provided at no charge with each Port Termination. The
NTN assignment is independent of the customer's voice telephone number.
Optional Features
Certain optional features and functions are available depending on the serving packet switch.
Call Redirection - Automatically redirects calls addressed to a primary DTE, to a secondary DTE
when the primary DTE is not in service, busy or designated for call redirection due to network
operator request. Call redirecting ends automatically when access to the primary DTE is again
possible.
Closed User Group (CUG) - A private group of users that limits communications to members
within the group. The CUG allows its members to transmit and receive calls, service type
permitting, to and from other members within the CUG.
Direct Call - Enables a user to automatically establish a virtual call to a predetermined NTN.
Fast Select Acceptance - Allows the customer to terminate fast select calls that originated from
an end user's DTE. The fast select data is delivered to the terminating customer in the user data
field of an incoming call packet. The terminating DTE then responds with either a call accepted
packet or a call clear indication.

Optional Features (cont’d)
Hunt Group - An association of ports with a single or multiple NTNs. Two features are available.
The homing feature allows terminating calls to be distributed sequentially over the ports.
Non-homing allows terminating calls to be distributed equally over the ports.
Multiple Network Terminal Numbers - Permits the user to have additional DTE addresses per
port, thereby, permitting incoming logical transmissions to be routed by the PSN to the
appropriate DTE. The available quantity of this feature may be limited by the Company.
Network User Identification (NUI) - A numeric character string, defined by the Company, used as
a log-on ID. In the case of the dedicated access, the NUI may correspond to the network
address.
Permanent Virtual Circuit - Establishes a logical channel between two NTNs and remains
indefinitely in the data transfer mode.
Reverse Charging - Allows the originating NTN's PSN usage and holding time charges to be
billed to the terminating NTN on a per session basis. The call will be set up only if the terminating
NTN is configured to accept charges.
Reverse Charging Acceptance - Authorizes the terminating NTN to accept PSN usage and
holding time charges from an originating NTN.
Usage Charges
Fast Select
Allows for a call request, the transmission of data and call clearing in a single exchange of
packets. These packets may contain up to 128 data octets in addition to the call request

Usage Charges (cont’d)
Data Transport
Charges apply for ISDN X.25. ISDN Interface usage charges apply for X.75 Dedicated Access
Arrangements whose PSN switching is limited to a single ISDN switch in a LATA.
Customers who access the network via ISDN X.25 packet lines and transmit an average of 2.0
kilosegments or less of data per logical session per minute can choose between minutes of use
(MOU) and kilosegment billing. Customers who transmit greater than an average of 2.0
kilosegments per logical session per minute will be billed for kilosegments transmitted. The
average kilosegments per minute will be calculated for the billing period for rating purposes.
The measurement of a MOU session begins upon receipt of the call acceptance packet and ends
upon receipt of the call clear packet. The minimum initial MOU session is 7 tenths of a minute
and additional usage is measured in tenths of minutes. MOUs will be accumulated for the billing
period for rating purposes.
Kilosegment measurement counts the number of segments transmitted. A kilosegment is 1000
segments. A segment has a billable length of 64 octets of customer information. The minimum
initial session is 40 segments and additional usage is measured in segments. Segments are
totaled at the end of the billing period and rounded to the next whole kilosegment for rating
purposes.
ISDN Interface
The ISDN Interface is for the purpose of allowing other networks to terminate directly onto an
ISDN Integrated Packet Handler (IPH). This will give the other network access to the ISDN lines
served by that IPH and only that IPH. They must connect on an X.75 port connection in addition
to the digital private line.

Closed User Groups
Closed User Groups (CUGs) provide a mechanism for creating private networks that restrict
communications between group members and non-members in various ways. The standard
CUG permits members to communicate with each other but precludes communication with nonmembers. The standard CUG feature may be modified to allow CUG members to communicate
with other CUGs or network users and to restrict calling within a CUG. The standard CUG
modification options include:
-
Incoming Calls Barred (within CUG) - prohibits certain members from receiving incoming calls
from others in the same CUG.
-
Outgoing Calls Barred (within CUG) - prohibits certain members from placing outgoing calls to
others within the CUG.
-
Incoming Access (other CUG members or network users) - permits CUG members to
communicate with one another and to receive calls from PSN customers who do not belong to
any CUG, or from PSN customers who belong to other CUGs with outgoing access capability.
-
Outgoing Access (other CUG members or network users) - permits CUG members to
communicate with each other and to originate calls to other PSN customers who do not
belong to any CUGs or PSN customers who belong to other CUGs with incoming access
capability.
