INSTALLING THE CABINETS
Unpacking |
Site Requirements |
Unpack the equipment and check it against your equipment lists. Inspect for physical damage. If you are not sure about a component’s function, review the Product Description Manual. Contact your Sales Representative if you have additional questions.
Have the appropriate tools for the job on hand, including: a test set, a punch down tool and a digital voltmeter.
Before Installing
Make sure you have a building plan showing the location of the common equipment, extensions, the telco demarcation and earth ground. In addition, the installation site must meet the requirements outlined in the Standard Practices Manual.
1. Installing
Cabinets
The common equipment is contained in three wall-mounted cabinets: the Main Cabinet and two Expansion Cabinets. Choose a central location for the cabinets that allows enough space for the equipment — and provides enough room for you to comfortably work. The Installation Layout (Figure 1-4 and Figure 1-5 on pages 1-6 and 1-7) shows you about how much space your system requires.
Each common equipment cabinet requires a three-prong dedicated 110 VAC 60 Hz circuit (NEMA 5-15 receptacle) located within 7 feet of the AC receptacle. You should install the extension and trunk blocks to the right of the Main Cabinet. Telco should also install the RJ21X to the right of the Main Cabinet.

28i Hardware Information
The 28i system uses software comparable to the 124i base system. This means that any features that are available in the 124i base system are available in the 28i system as long as the software level is the same. Check with your sales representative for the availability of DID and BRI trunks.
System Load Factors
When connecting equipment to the 28i system, always consider the Load Factor Table. This table shows the relative power requirements for each device that you can connect. The following PCB’s have no load factor: 24CPRU, 4CIDU, 4DTDU, 4PGDU, 4ATRU, 8DSTU, and LAPB. In order not to exceed the load factor, the system should not exceed a maximum of two station PCBs (either 8DSTU or 4ASTU).
To use the Load Factor Table:
1.Multiply the number of devices (column 4) by their load factor (column 3).
For example, 16 key telephones plus 1 ASTU have a load factor of 23.
2.Enter the result from step 1 in column 5 (Total Device Load).
3.Add up all the entries in column 5. Total cabinet load cannot exceed 23.

2.PCB Installation and Startup
INSTALLING PCBs
To install the 28i system’s CPRU PCB:
1.Insert the battery into the battery clips.
2.Plug the CPRU into KSU CPRU slot (Slot 1).
3.When powering up, hold down the COLD switch on the CPRU.
This ensures that the system will load the default database on initial power-up.
On initial power up (with a cold startup), the system scans for station ports from the lowest slot to the highest slot, so the first 8 station ports on the 24CPRU are assigned extension numbers 301-308 automatically. The next station card that follows, no matter which slot it’s in, starts at extension 309.

Digital Station (DSTU) PCB (Figure 2-10)
The Digital Station (DSTU) PCB provides DDK connectors for eight digital telephones, VAU, 3-ACI, 2-DCI, or 2-OPX modules.
To install a DSTU PCB:
1.28i: Plug a DSTU PCB into slot 2 in the KSU (1 DSTU PCB maximum per system).
124i: Plug DSTU PCBs into slots 1-3 in any installed cabinet (nine maximum).
2.Refer to Part 3: Installing Extensions and Trunks for cabling instructions.
On initial power-up (28i: hold down the Cold Start switch / 124i: CPRU Mode Switch set to Cold), the slot into which you plug a station PCB determines its associated extension numbers. The system scans for station PCBs from the lowest slot in the first cabinet (Main) to the high slot in the last cabinet (Expansion # 2). The first station PCB the system finds gets extension numbers 301-308. The next slot gets extension numbers 309-316, etc.
After initial power up (28i Hot Start without holding down any switch / 124i: CPRU Mode Switch set to Hot), any new station PCBs you plug in automatically add to the top of your exten-

sion number list. For example, if your highest extension port is 324, any new station PCB you plug in will start with extension number 325. This is true regardless of the slot number used.

T1/PRI (PRIU) Interface PCB (Figure 2-11)
Note: For PRI, please consult with your Nitsuko
Representative for availability.
For T1 and ISDN Primary Rate Interface (PRI) applications, install a T1/PRI Interface PCB. This PCB has a single 24-channel circuit which can be configured for either T1 trunks or PRI. The T1/PRI PCB requires an Advanced Features Module (EXCPRU) and, for DTMF receivers, a Tone Detector (DTDU) PCB.
If set for T1, the T1/PRI PCB provides 24 trunks in a single slot. These trunks can be one of the following:
●Loop Start
●Ground Start
●DID
●Tie Lines
●ANI/DNIS Tie Lines
If set for PRI, each T1/PRI PCB provides 24 PRI (23 B&D) channels and supports the following PRI services:
●Basic PRI Call Control (BCC)
●Display of incoming caller’s name and number
●Routing based on the number the caller dials
●ISDN maintenance functions (e.g., In Service/Out of Service Messaging)
●Speech and 3.1 KHz audio
The T1 feature requires that the Base CPU version level must
be one of the following: |
