2016S Shumway wiring
M2016S have a relay circuit to disconnect the handset when on-hook (on-hook security), and require an external power supply to function, eg: Shumway SBI-217-25 (42VDC @ 300mA), or PSU. The following shows how the external power supply is connected.
The M2016S requires a 6 conductor line cord, the wall jack may be either RJ-12 (6 pin) or RJ-45 (8 pin).
1 - Shumway (White)
3 - Ring
4 - Tip
6 - Shumway (Blue)
Shumway is not polarity sensitive,
2 - Shumway (Orange*)
4 - Ring
5 - Tip
7 - Shumway (White-Brown)

Frame Room / IDF:
- Each M2016S+Shumway instance requires two house-cable pairs: one for the TN, and one for power.
- A standard T686B/T686A station drop 'splits' the Orange (or Green), and Brown pairs for power.
For example, with Cat5 station tails terminated on a QCBIX1A4 block:
Phone jack wired T686B: TN to Blue-pair (pair 1),|
Shumway to Orange (pin 4) and White/Brown (pin 7)
Phone jack wired T686A: TN to Blue-pair (pair 1),|
Shumway to Green (pin 6) and White/Brown (pin 7)
AC (wall-wart) power supplies are for loops of 30m (100ft) or less. DC power is required for loop lengths of 200m (650ft) or less.
You will hear the 2016's relay "click" when power is correctly applied (with or without TN). A working TN is required for dial-tone!
- AC power: 29 V AC, 700 mA isolated (240VAC/50Hz: AO367914 / 120VAC/60Hz: AO367335)
- DC power: 42 V DC, 300 mA isolated, with current limiting output of 1 amp (Shumway).
M2016S Secure Set Connections.
The M2016S red LED triangle will light steadily when off-hook, or ringing (eg, handset/piezo relays are connected) and blink for "message waiting". The M2016S has no handsfree capability, nor does it support any accessories, options, or add-on modules.
