Overview

Description of the ISDN Interface

The ISDN Interface is a Primary Rate Interface (PRI) digital trunk card that provides 23 voice channels (“B” channels) and a control channel (“D” channel) over a four-wire circuit.
ISDN lines can be leased from local exchange carriers and long-distance carriers.
Note: The current version of the ISDN supports voice communications only. Data can be transmitte d only if i t reache s the IS DN in ana log form. Exampl es of analog data that can be transmitted over the ISDN include fax transmissions or PC files that have been converted into analog form using a modem.

Framing Options

The ISDN Interface takes an 8-bit sample from each of the 23 voice channels. These samples are grouped into 23 bearer time slots, and 1 data channel time slot.
Since each of the 24 time slots contains 8 bits, the number of s ampling bi ts i n each frame equals 192 (24 x 8 = 192). In addition, a framing bit is added to the end of each frame to mark where the frame ends. The addition of the framing bit results in a 193-bit frame.
The ISDN transmits these 193-bit frames at a rate of 8000 per second. The total number of frames (193) multiplied by the frame speed (8000 per second) results in a total transmission rate of 1.544 Mbps.
ESF Framing Formats
The extended superframe (ESF) format transmits the sampling frames in groups of 24 with 23B (bearer) channels at 64 Kbps and 1D (Data) channel at 64 Kbps. With the addition of 2.0 Kbps error checking CRC, 2.0 Kbps framing, and 4.0 Kbps datalink facility, the total capacity is 1.544 Mbps.

Pre-Installation Requirements

Introduction to the ISDN Interface
Pre-Installation Requirements
Use the following guidelines to prepare your site for ISDN installation.

Ordering ISDN

The ISDN PRI provides a flexible method of providing access to the PSTN (Public Switched Telephone Network). Because of the numerous ways that an ISDN span can be configured by the CO, it is essential that the DBS configuration and the provisioning of the CO be compatible. The following tables are provided to identify the critical parameters that must be set for proper operation. The following tables provides a list of information that must be gathered about the CO as well as the type of information which the CO will need to know regarding the DBS system.
# Information Needed from CO Comments / Examples

CSU Equipment
The installer must provide a Channel Service Unit (CSU) plus CSU cabling. The CSU equipment must meet the specifications contained in T able 1-3. See
page 2-12 for instructions on installing the CSU.
Table 1-3. CSU equipment required for ISDN
Item Specifications Vendors
CSU
CSU Cabling
The Channel Service Unit (CSU) must comply with FCC Part 15 and Part 68. The CSU is installed between the DBS and the public network. The CSU provides alarm, diagnostic, and monitoring functions, as well as network protection.
Each CSU requires a network cable and an equip­ment cable. The network cable connects from the CSU to the network interface. The equipment cable connects from the CSU to the DBS ISDN MDF card.
For Kentrox CSUs
The network cable requires a female DB-15 con­nector and an RJ48C connector. The equipment cable requires a male DB-15 connector and an RJ48C connector.
To simplify installation, you can order the prefabri­cated cables shown in the “Vendors” column.
If you fabricate your own ISDN cables, you should use 24 AWG stranded cable that includes shielding for each pair. For best results, use the cable listed under “Vendors.”
For Premier CSUs
You must fabricate your own cables for the Premier CSU. The network cable requires two RJ48C con­nectors. The equipment cable connects to an RJ48C connector on the ISDN MDF card and to four screw-down terminals on the CSU.
For both cables, use 24 AWG stranded cable that includes shielding for each pair. For best results, use the cable listed under “Vendors.”
The following CSUs have been used suc­cessfully with the DBS ISDN.
Kentrox Kentrox T-SERV II or Kentrox T-SMART (Kentrox can be contacted at 1-800-733-
5511.)
For Kentrox CSUs
Kentrox offers prefabricated cables f or their CSUs. For the network cable, order part number 01-
93010151. For the equipment cable, order part number 01-93010121. If you fabricate your own cables, use 24 AWG stranded cable that includes shielding for each pair.
Belden (Richmond, IN) offers stranded cable that complies with these specifications. Order part number 8723.

Installation Guidelines

Guidelines

Read the following guidelines before beginning ISDN installation. Installation instructions begin on page 2-14.

Hardware Requirements

• The system configuration determines what cards and cables must be purchased for ISDN. See “DBS Equipment” on page 1-8 for more information.
• The installer must provide a Channel Service Unit (CSU) that complies with FCC Part 15 and Part 68. The CSU is installed between the DBS and the public network. The CSU provides alarm, diagnostic, and monitoring functions, as well as network protection.
See “CSU Equipment” on page 1-9 for details on purchasing CSUs.

Maximums

• One ISDN card can be installed per cabinet; the ISDN card must be installed in the “EC/TRK” slot.
• The number of ISDN cards that can be installed in two-cabinet systems depends on the sizes of the connected systems. Table 2-1 shows ISDN maximums for two-cabinet systems.
Note: The DBS 72 + DBS 40 combination does not support ISDN.

Revised April 2000 DBS-EX23-530 2-3
Guidelines
Installation
Fractional ISDN can be used when fewer than 23 ISDN trunks are needed. Fractional ISDN allows you to use only a portion of the 23 channels provided on the ISDN card.
• Fractional ISDN per port assignments require the VB-43511A version of the loop start trunk card. The older VB-43511 version may be used with fractional ISDN but requires that the trunks be assigned in blocks of 8.
• Though each ISDN Interface provides 23 trunk channels, ISDN trunks do not increase the overall trunk capacity of the DBS. Each ISDN channel subtracts from the total number of analog trunks that can be installed. The number of analog trunks that can be used are decremented in quantities of 1 for each ISDN channel user.
Tables 2-2 through 2-4 show the possible combinations of analog and digital trunks assignments based on system size.
The trunk numbering shown in these tables is determined by backplane trunk port assignments. Therefore, the numbering cannot be changed.
Note: Analog trunks are numbered beginning with “1.” ISDN trunk channels are numbered beginning with the highest trunk channel used.
2-4 DBS-EX23-530 Revised April 2000
Installation Guidelines

Trunk Assignments for Single-Cabinet Systems

• Programming is not required to associate trunk ports with slot locations. However, you must use programming to specify that a combination of ISDN and analog trunks is installed, and you must also specify how many ISDN channels are used.
• Fractional ISDN per port assignments require the VB-43511A version of the loop start trunk card. The older VB-43511 version may be used with fractional ISDN but requires that the trunks be assigned in blocks of 8.

Trun k Ass ign men ts for Double-Cabinet Systems

• When ISDN is used in a two-cabinet system, the number of ISDN channels that can be assigned in each cabinet depends on the master/slave designation.
• Fractional ISDN per port assignments require the VB-43511A version of the loop start trunk card. The older VB-43511 version may be used with fractional ISDN but requires that the trunks be assigned in blocks of 8.
The following table shows the maximum number of ISDN channels that can be assigned in two-cabinet systems.

• Two-cabinet systems use the same trunk numbering scheme as single­cabinet systems: analog trunks are numbered from “1” upward; ISDN trunk channels are numbered downward from the highest channel used.
Tables 2-6 through 2-10 show trunk numbering for two-cabinet systems using the maximum number of ISDN channels.
